[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figures 1 to 8 As shown, a cable intermediate joint detection device according to an embodiment of the present invention comprises a fixing plate 1, a wireless communication component 11 is installed on the top of the fixing plate 1, upper fixing seats 2 are fixed on both sides of the fixing plate 1, a lower fixing seat 21 is arranged below the upper fixing seat 2, an infrared temperature sensor 23 is arranged between the upper fixing seats 2, an intermediate joint 3 is arranged between the upper fixing seat 2 and the lower fixing seat 21, the intermediate joint 3 is arranged between the two upper fixing seats 2, a cable 5 is arranged inside the intermediate joint 3, an air intake shell 4 is fixed on one side of one of the upper fixing seats 2, and the air intake shell 4 is arranged inside the air intake shell 4. A fan 41 is installed on the bottom of the air inlet housing 4, an air inlet pipe 42 is fixed to the bottom end of the air inlet housing 4 through a hose, and the other end of the air inlet pipe 42 is inserted between the middle joint 3 and one end of the cable 5, an air outlet housing 44 is fixed to one side of the other upper fixing seat 2, an air outlet pipe 43 is fixed to one end of the air outlet housing 44 through a hose, and the other end of the air outlet pipe 43 is inserted between the middle joint 3 and the other end of the cable 5, a thermistor 441 is installed inside the air outlet housing 44, a humidity sensor 442 is provided on one side of the thermistor 441, and the humidity sensor 442 is installed inside the air outlet housing 44;

[0032] When the ends of the two cables 5 are connected, the middle joint 3 is needed to wrap the ends of the cables 5. During use, the internal state of the middle joint 3 needs to be detected to ensure that it is in a stable state. Before use, the two sets of upper fixing seats 2 and lower fixing seats 21 are put on the two ends of the middle joint 3. At this time, the middle joint 3 can be fixed under the fixing plate 1. When the cable 5 is used, heat will be generated, and the heat will be conducted through the middle joint 3. At this time, the infrared temperature sensor 23 can detect the heat on the surface of the middle joint 3, but the infrared temperature sensor 23 cannot detect the temperature inside the middle joint 3 more accurately. Therefore, when sealing the cable 5 and the middle joint 3, the air inlet pipe 42 is inserted into the gap on both sides of the cable 5 and the middle joint 3, and then the gap between the cable 5 and the middle joint 3 is sealed, and the air outlet pipe 42 is inserted into the gap on both sides of the cable 5 and the middle joint 3. 43 is inserted into the gap and sealed. When in use, the fan 41 is started to blow air into the interior of the air intake shell 4. At this time, the air intake shell 4 inputs the airflow into the interior of the intermediate joint 3 through the air intake pipe 42. At this time, the airflow enters the interior of the intermediate joint 3 and absorbs the heat inside the intermediate joint 3. Then the heat can be discharged to the interior of the air outlet shell 44 through the air outlet pipe 43. The thermistor 441 inside the air outlet shell 44 can detect the output airflow temperature. The change in the airflow temperature can be used to determine whether the interior of the intermediate joint 3 is in a normal state. At the same time, the humidity sensor 442 can detect the humidity in the airflow. When the humidity in the airflow is high, there may be leakage inside the intermediate joint 3. At this time, a signal is sent through the wireless communication component 11, and the detected information can be transmitted to the receiving end, which is convenient for the staff to judge the situation.

[0033] like Figure 7 As shown, a dustproof net 411 is fixed to the top of the air intake housing 4;

[0034] When the fan 41 draws air into the air intake housing 4, dust and impurities may exist in the external air. After the dust and impurities enter the air intake housing 4, they may block the air intake pipe 42, affecting subsequent use.

[0035] like Figure 8 As shown, a flip baffle 443 is rotatably connected to one side of the air outlet housing 44 away from the upper fixing seat 2;

[0036] During the process of air outlet from the air outlet shell 44, the flip baffle 443 is pushed open by the air flow, and the air outlet shell 44 can be exhausted at this time. When the exhaust is completed, the flip baffle 443 will flip downward due to its gravity. At this time, the flip baffle 443 can be flipped and cover the air outlet end of the air outlet shell 44, so as to prevent foreign objects from entering the air outlet shell 44 when not in use and affecting subsequent use.

[0037] like Figures 1 to 5 As shown, a rotation groove 26 is provided on one side of the upper fixing seat 2 and the lower fixing seat 21 close to the infrared temperature sensor 23, and a first movable semi-ring 24 is rotatably connected to the interior of the upper fixing seat 2 through the rotation groove 26, and a second movable semi-ring 241 is rotatably connected to the interior of the lower fixing seat 21 through the rotation groove 26, and a support frame 22 is fixed between the two first movable semi-rings 24, and the infrared temperature sensor 23 is arranged below the support frame 22;

[0038] When detecting the external temperature of the middle joint 3, the rotation of the first movable semi-ring 24 drives the support frame 22 to rotate. At this time, the support frame 22 drives the infrared temperature sensor 23 to rotate around the middle joint 3. The infrared temperature sensor 23 can detect the temperature outside the middle joint 3. During the rotation of the first movable semi-ring 24 inside the rotating groove 26, the second movable semi-ring 241 will rotate simultaneously with the first movable semi-ring 24, so as to drive the infrared temperature sensor 23 to rotate and detect the temperature at different positions of the middle joint 3.

[0039] like Figures 5 and 6As shown, a plurality of teeth 261 are fixed at equal intervals on the inner side of the rotating groove 26, a steering gear 242 is rotatably connected to the top end inside the first movable semi-ring 24, a part of the tooth surface of the steering gear 242 protrudes outside the first movable semi-ring 24, the steering gear 242 is meshedly connected with the teeth 261, and the end of the steering gear 242 close to the support frame 22 is rotatably connected with the second bevel gear 243 through the output shaft, a second motor 224 is installed on the side of the top end of the support frame 22 close to the steering gear 242, an output bevel gear is fixed to the end of the rotating shaft of the second motor 224, the second bevel gear 243 is placed inside the support frame 22, and the second bevel gear 243 is meshedly connected with the output bevel gear of the second motor 224;

[0040] When the first movable half ring 24 needs to rotate, the second motor 224 is started to rotate. At this time, the second motor 224 drives the second bevel gear 243 to rotate, and the second bevel gear 243 drives the steering gear 242 to rotate. At this time, the steering gear 242 is engaged with the teeth 261 to rotate the first movable half ring 24. At this time, the first movable half ring 24 can drive the infrared temperature sensor 23 to rotate.

[0041] like Figures 1 to 6 As shown, a sliding hole is provided inside the support frame 22, and a moving block 221 is slidably connected inside the sliding hole, and a bidirectional screw rod 222 is rotatably connected inside the sliding hole, and the bidirectional screw rod 222 and the moving block 221 are threadedly connected, and one end of the bidirectional screw rod 222 close to the second motor 224 is rotatably connected to the first bevel gear 223, and the first bevel gear 223 is meshed with the output bevel gear of the second motor 224. The first bevel gear 223 and the bidirectional screw rod 222 are connected by a ratchet ratchet structure, and the output shaft end of the steering gear 242 is also connected to the second bevel gear 243 by a ratchet ratchet structure, and the infrared temperature sensor 23 is arranged below the moving block 221;

[0042] When the surface temperature of the intermediate joint 3 is detected, in order to make the detection more accurate, it is necessary to measure multiple points on the surface of the intermediate joint 3. During the measurement, the second motor 224 is started to rotate. At this time, the second motor 224 rotates to drive the second bevel gear 243 and the first bevel gear 223 to rotate. At this time, the ratchet teeth of the ratchet wheel inside the second bevel gear 243 are engaged, and the ratchet teeth of the ratchet wheel inside the first bevel gear 223 are separated, so that the second bevel gear 243 can drive the steering gear 242 to rotate to make the first movable semi-ring 24 rotate in the same direction. When the first movable semi-ring 24 After rotating to the appropriate direction, the infrared temperature sensor 23 can be used for detection, and at the same time, the second motor 224 is rotated in the opposite direction. At this time, the ratchet teeth inside the second bevel gear 243 are separated, and the ratchet teeth inside the first bevel gear 223 are engaged, which can drive the bidirectional screw rod 222 to rotate. At this time, the bidirectional screw rod 222 drives the moving block 221 to slide inside the support frame 22, and the moving block 221 can drive the infrared temperature sensor 23 to move left and right, so that the infrared temperature sensor 23 can detect the temperature on the surface of the middle joint 3 more comprehensively.

[0043] like Figures 1 to 3 As shown, a sliding groove is provided in the middle of the upper fixed seat 2 and the lower fixed seat 21, a positioning plate 25 is provided inside the upper fixed seat 2, a telescopic column is fixed to the top of the positioning plate 25, and the telescopic column is inserted into the sliding groove of the upper fixed seat 2, and a positioning plate 25 and a telescopic column are also provided inside the lower fixed seat 21, and the positioning plate 25 inside the lower fixed seat 21 is set at a symmetrical position with the positioning plate 25 inside the upper fixed seat 2, and the internal thread of the telescopic column is connected with a threaded rod 251, and the threaded rod 251 is rotatably connected to the top of the upper fixed seat 2;

[0044] During the installation process, the upper fixing seat 2 and the lower fixing seat 21 are sleeved on the two ends of the middle joint 3. At this time, the fixing plug plate 211 is connected to the sliding grooves on both sides of the upper fixing seat 2, and they are fixed by bolts. Then, the threaded rod 251 is screwed to make the telescopic column of the positioning pressure plate 25 extend from the inside of the sliding groove. The telescopic column pushes the positioning pressure plate 25 close to the middle joint 3. The two positioning pressure plates 25 approach the middle joint 3 at the same time and clamp it therebetween, so as to fix the middle joint 3 and position it at the center of the upper fixing seat 2 and the lower fixing seat 21, which is convenient for the detection of the infrared temperature sensor 23. When using middle joints 3 with different outer diameters, the extension length of the telescopic column of the positioning pressure plate 25 can be adjusted.

[0045] like Figures 1 to 3As shown, a first rotating rod 253 is rotatably connected to one side of the upper fixed seat 2, and a second rotating rod 254 is rotatably connected to one side of the lower fixed seat 21 near the first rotating rod 253. The first rotating rod 253 and the upper threaded rod 251 are connected by a belt and a pulley, and the second rotating rod 254 and the lower threaded rod 251 are also connected by a belt and a pulley. A toothed disc 252 is fixed to the top of the upper threaded rod 251, and a first motor 12 is installed at the top of the fixed plate 1. A transmission rod 121 is provided on the side of the first motor 12 near the wireless communication component 11, and the transmission rod 121 is rotatably connected to the top of the fixed plate 1. An output gear is fixed to the end of the rotating shaft of the first motor 12, and a gear is fixed to the middle of the transmission rod 121. The output gear is meshed with the gear in the middle of the transmission rod 121. Gears are fixed to both ends of the transmission rod 121, and the gears at both ends are respectively meshed with the tops of the toothed discs 252 on both sides.

[0046] When fixing the middle joint 3, it is necessary to fix its two ends at the same time. At this time, start the first motor 12 to drive the transmission rod 121 to rotate. The transmission rod 121 drives the toothed disc 252 to rotate through the gears at both ends. The toothed disc 252 drives the threaded rod 251 to rotate, and at the same time drives the first rotating rod 253 to rotate through the belt pulley. At the same time, the first rotating rod 253 drives the second rotating rod 254 to rotate, and the second rotating rod 254 can drive the threaded rod 251 below to rotate. At this time, the positioning pressure plates 25 on both sides can clamp the middle joint 3 at the same time, so that the middle joint 3 is in the middle of the upper fixed seat 2 and the lower fixed seat 21.

[0047] like Figure 3 to Figure 4 As shown, a docking groove 255 is fixed at the bottom end of the first rotating rod 253, and a docking block 256 is fixed at the top end of the second rotating rod 254. The docking block 256 can form a snap-fit ​​structure with the docking groove 255;

[0048] The upper fixing seat 2 and the lower fixing seat 21 will be separated before use, and the second rotating rod 254 and the first rotating rod 253 are in a separated state. When the upper fixing seat 2 and the lower fixing seat 21 are installed together, the docking block 256 will be inserted into the docking groove 255, and the first rotating rod 253 and the second rotating rod 254 can be connected and rotated synchronously.

[0049] like Figure 6 As shown, a telescopic shell 231 is fixed to the top of the infrared temperature sensor 23, a support rod 234 is fixed to one side of the telescopic shell 231, a movable ball 235 is rotatably connected to the bottom end of the support rod 234, a spring 232 is fixed to the bottom end of the telescopic shell 231, a fixing column 233 is inserted into the top of the telescopic shell 231, the top of the fixing column 233 is fixedly connected to the moving block 221, and the bottom end of the fixing column 233 is fixedly connected to the spring 232;

[0050] When in use, the outer diameter of the middle joint 3 will be different. To ensure the detection accuracy of the infrared temperature sensor 23, it is necessary to keep the distance between it and the middle joint 3 at the same position. Therefore, when in use, the support rod 234 will be supported on the surface of the middle joint 3. At this time, the infrared temperature sensor 23 can be kept at the same distance from the middle joint 3. The movable ball 235 can roll when the moving block 221 drives the infrared temperature sensor 23 to move, thereby reducing the friction between the support rod 234 and the middle joint 3. When the outer diameter of the middle joint 3 is different, the height to which the support rod 234 is pushed up will also change. At this time, the support rod 234 drives the telescopic shell 231 to rise, and the spring 232 can be squeezed by the fixed column 233 inside the telescopic shell 231, so as to realize automatic adjustment of the position of the infrared temperature sensor 23 so that it can be kept at the same distance from the middle joint 3 with different outer diameters.
