Description

Technical Field

[0002] At present, many equipment in power plants use motors. Some motors are under high load or internal stress or other abnormal circuit short circuits. When the shaft temperature of some motors is too high during operation, there will be systemic risks.

DETAILED DESCRIPTION

[0025] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0027] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0028] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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 a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0029] like Figure 1 As shown, in some embodiments of the present application, a self-service mobile inspection device is provided, which includes a detection part 100, a telescopic part 200, a driving part 300 and a steering part 400, wherein the detection part 100 is arranged at the top of the telescopic part 200, and the driving part 300 and the steering part 400 are arranged at the bottom of the telescopic part 200.

[0030] In some embodiments of the present application, Figure 3 As shown, the telescopic part 200 includes a telescopic rod 210, a telescopic seat 220 and a long rod motor 230. The telescopic rod 210 and the telescopic seat 220 are cylindrical structures. The long rod motor 230 is arranged inside the telescopic rod 210, and the telescopic rod 210 is arranged inside the telescopic seat 220. The telescopic rod 210 is telescopically connected to the telescopic seat 220.

[0031] Specifically, the inner wall and outer wall of the telescopic rod 210 are respectively provided with internal threads and external threads, the inner wall of the telescopic seat 220 is provided with an inner wall thread, the external thread of the telescopic rod 210 matches with the inner wall thread of the telescopic seat 220, the bottom of the long rod motor 230 is fixedly set at the bottom of the telescopic seat 220, and an adapter block 231 is provided on the top of the long rod motor 230, and the adapter block 231 is provided with threads, and its threads match with the internal threads of the telescopic rod 210.

[0032] After the long rod motor 230 is turned on, the adapter block 231 at its top rotates together with the motor. The adapter block 231 moves up and down relative to the telescopic rod 210 through rotation. Since the height of the adapter block 231 does not change, the telescopic rod 210 rises or falls along the telescopic seat 220 under the drive of the adapter block 231.

[0033] In some embodiments of the present application, Figure 2 and Figure 7 As shown, the driving part 300 and the rotating part are jointly arranged at the bottom of the telescopic seat 220 to drive the inspection device to move or turn.

[0034] The driving unit 300 includes a driving wheel 310, a driving motor 320 and a transmission belt 330, wherein the driving wheel 310 is a structure in which a transmission shaft is arranged between two wheel bodies, one end of the transmission belt 330 is connected to the driving motor 320, and the other end of the transmission belt 330 is connected to the transmission shaft. After the driving motor 320 is turned on, the driving motor 320 drives the transmission belt 330 to rotate, and then drives the transmission shaft to rotate. The driving wheels 310 at both ends of the transmission shaft rotate together with the transmission shaft, thereby realizing the movement of the driving wheel 310.

[0035] In some embodiments of the present application, Figure 1 and Figure 2 As shown, the driving wheel 310 has a convex structure on both sides and a concave structure in the middle. This design makes the driving wheel 310 have less friction with the ground, less resistance, and runs more labor-saving and smoother.

[0036] The driving wheel 310 also includes a wear-resistant ring 311, which is sleeved on the concave position in the middle of the driving wheel 310, and the wear-resistant ring 311 is interference fit with the driving wheel 310. The maximum diameter of the wear-resistant ring 311 is slightly smaller than the maximum diameter of the steering wheel 410. If on a flat road, only the driving wheel 310 contacts the ground. If on a rugged road, the equipment will be a little powerless during operation. At the same time, the wear-resistant ring 311 in the middle of the driving wheel 310 will also contact the convex ground. Because the friction between the middle wear-resistant ring 311 and the convex ground is large, there is a large driving thrust to push the equipment forward, so that the equipment will not slip or move backward due to insufficient power due to the rugged and uneven ground.

[0037] In some embodiments of the present application, Figure 1 , Figure 3 and Figure 6 As shown, the steering part 400 includes a steering wheel 410, a steering motor 420 and a bogie 430, wherein one end of the bogie 430 is an end head, and the other end of the bogie 430 is two end heads, and the end heads are provided with two support rings. The steering motor 420 is connected to one end of the bogie 430 to drive the bogie 430 to rotate. The rotating part also has a support shaft, and the rotation axis of the steering wheel 410 and the support ring are jointly sleeved on the support shaft.

[0038] The steering part 400 also includes a first bearing 440 and a second bearing 450. The first bearing 440 is arranged between the steering wheel 410 and the support shaft, and the second bearing 450 is arranged between the support ring and the support shaft. The function of the multiple bearings is to enable the steering wheel 410 to play a secondary acceleration role when moving forward, so that the operation is smoother.

[0039] In some embodiments of the present application, Figure 4As shown, the detection unit 100 is arranged at the top of the telescopic rod 210, and changes its height position as the telescopic rod 210 rises or falls, and changes its plane coordinates as the driving unit 300 and the rotating unit move, so as to reach a preset position.

[0040] The detection unit 100 includes a dot matrix projection device 110 and an infrared temperature measurement device 120, wherein the dot matrix projection device 110 is used to obtain the position information of the motor shaft, and the infrared temperature measurement device 120 is used to obtain the temperature information of the motor shaft.

[0041] In some embodiments of the present application, the inspection device also includes a rain sensing unit 600, which includes a transparent cover 610 and a floodlight sensor. The transparent cover 610 is set in an unobstructed position of the inspection device. The floodlight sensor senses the light refraction information on the transparent cover 610 to determine whether it is raining. If it fails to determine that it is raining, the inspection device will automatically run to a corner of the workshop or a specific rain shelter to prevent heavy rain from damaging the equipment.

[0042] In some embodiments of the present application, the inspection device also includes a receiver and a speaker 700 .

[0043] In some embodiments of the present application, the inspection device is also provided with a control unit 500, which is used to control the operation of the detection unit 100, the telescopic unit 200, the driving unit 300, the rotating unit, the rain sensing unit 600, the earpiece and the speaker 700.

[0044] In order to ensure the safe operation of the motor shaft, the control unit 500 is configured to preset a safe temperature range for the normal operation of the motor shaft.

[0045] When the temperature of the motor shaft is within the safe temperature range, it can perform normal work without causing damage to the equipment or risk of fire.

[0046] In order to detect the motor shaft, the control unit 500 is configured to obtain position information of the motor shaft and generate an effective monitoring range of the motor shaft.

[0047] Specifically, the position information of the motor shaft is obtained by using the dot matrix projection device 110, and the image information of the motor shaft is preset in the control unit 500. The dot matrix projection device 110 obtains image data in the environment by patrolling the surrounding environment, and compares the image data and the image information. When the image data and the image information are consistent, the position of the motor shaft is determined.

[0048] In order to detect the motor shaft, the controller is configured to obtain the height characteristics of the motor shaft after moving to the effective detection range.

[0049] Specifically, according to the acquired position information, the control unit 500 controls the driving unit 300 and the steering unit 400 to drive the steering motor 420 and the driving motor 320 to move the inspection equipment into the effective detection range, and the dot matrix projection device 110 acquires the image data of the motor shaft to obtain the height characteristics of the motor shaft.

[0050] In order to obtain the temperature of the motor shaft, the control unit 500 is configured to obtain the temperature information after increasing or decreasing to a corresponding height characteristic.

[0051] Specifically, according to the height characteristics of the motor shaft, the telescopic rod 210 is raised or lowered to the corresponding height of the motor shaft by controlling the rotation angle of the long rod motor 230. In addition, a plurality of infrared temperature measuring devices 120 are provided, each of which measures the temperature of a position point of the motor shaft, thereby obtaining the temperatures of multiple position points in the motor shaft, and calculating the temperature information of the motor shaft according to the temperatures of the multiple position points.

[0052] In order to determine the state of the motor shaft, the control unit 500 is configured to determine whether the temperature information is greater than a safe temperature range.

[0053] When the temperature information is not greater than the safe temperature range, the motor shaft is confirmed to be safe and the next motor shaft is inspected. When the temperature information is greater than the safe temperature range, the control unit 500 sends a danger signal to the speaker 700, and the speaker 700 makes a sound to remind the staff that the motor shaft is abnormal.

[0054] In other embodiments of the present application, the inspection equipment is also provided with a communication unit, which can send danger signals through the staff's computer, mobile phone or other communication devices to remind the staff to check the motor shaft.

[0055] In some embodiments of the present application, the control unit 500 is also connected to the rain sensing unit 600. The floodlight sensor senses the light refraction information of the transparent cover 610. The control unit 500 determines whether the light refraction information is within the refraction range of the transparent cover 610. When it exceeds the refraction range of the transparent cover 610, there are water droplets on the transparent cover 610, and it is determined that it is raining. The control unit 500 controls the driving unit 300 and the steering unit 400 to move, so that the inspection equipment is moved to a rain shelter.

[0056] The working process of a self-service mobile inspection device proposed in the present application is as follows: image information of the motor shaft and a safe temperature range for normal operation of the motor shaft are preset in the inspection device. After the inspection device is turned on, the dot matrix projection device 110 obtains image data in the environment and compares the image data with the image information. When the image data and the image information are consistent, the position of the motor shaft is determined. The distance measurement function of the dot matrix projection device 110 is used to determine the position information of the motor shaft and generate an effective detection position range. The control unit 500 turns on the driving motor 320 and the steering motor 420 to rotate the driving wheel 310 and the steering wheel 410 to drive the inspection device to move within the effective detection range. The dot matrix projection device is then used to obtain the height characteristics of the motor shaft. According to the height characteristics, the control unit 500 turns on the long rod motor 230 to raise or lower the telescopic rod 210 to the height position of the motor shaft. The infrared temperature measuring device 120 obtains the temperature information of the motor shaft to determine whether the temperature of the motor shaft is within the safe temperature range. If it exceeds the safe temperature range, an alarm is issued through the speaker 700 to remind the staff to check the motor shaft.
