DETAILED DESCRIPTION

[0021] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0023] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0024] One of the preferred embodiments of the present application is as follows: Figures 1 to 5As shown, a transformer temperature, sound and insulation integrated monitoring system includes a power transformer 1 (transformer body), a mounting seat 2, a driving mechanism 9, a moving device 6, an adjusting device 7 and a detection component 8 (such as an infrared temperature detector). The power transformer 1 is installed inside the enclosure 3, the mounting seat 2 is slidably arranged on the inner side of the enclosure 3 along the outer periphery of the power transformer 1, the driving mechanism 9 is installed on the mounting seat 2, the moving device 6 is installed on the mounting seat 2 and connected to the driving mechanism 9, the adjusting device 7 is installed on the mounting seat 2 and connected to the driving mechanism 9, and the detection component 8 is installed on the adjusting device 7.

[0025] It is understandable that when the temperature of the transformer body is detected, when the driving mechanism 9 performs the first action, the moving device 6 can drive the detection component 8 to move horizontally along the outside (periphery) of the transformer body under the drive of the driving mechanism 9, so as to detect the temperature of the transformer body in the horizontal direction; when the driving mechanism 9 performs the second action, the adjusting device 7 can drive the detection component 8 to move vertically under the drive of the driving mechanism 9; that is, through the different actions of the driving mechanism 9, the detection component 8 can perform all-round temperature detection on the outside of the transformer body, without the need for manual temperature detection, thereby improving work efficiency and safety. This automated temperature detection method can not only ensure the normal operation of the equipment, but also detect problems in a timely manner and take measures to ensure the safety and stability of the transformer.

[0026] It should be noted that the power transformer 1 here does not only represent the transformer body, but can also be other electrical components that need to be detected, such as distribution boxes, generators, etc.; of course, the detection component 8 does not only monitor temperature, for example, it can also monitor humidity, sound (noise) and so on, that is, the detection component 8 can be composed of humidity sensors, sound sensors and temperature sensors, etc., and then monitor different data such as the humidity around the power transformer 1 and the sound (noise) generated when the power transformer 1 is running; and sound monitoring is mainly used to assist in judging the insulation, vibration and fault analysis of the power transformer 1.

[0027] One of the embodiments of the present application is as follows: Figure 3 and Figure 4 As shown, the moving device 6 includes a matching track rod 601 and a roller 602 . The track rod 601 is installed inside the enclosure 3 and surrounds the outside of the power transformer 1 . The roller 602 is rotatably installed at the bottom end of the mounting seat 2 and connected to the driving mechanism 9 .

[0028] Specifically, Figure 1As shown, since the transformer body is in a rectangular structure, the enclosure 3 can also adopt a rectangular frame adapted thereto, and the track rod 601 also has a rectangular structure. When the detection component 8 needs to move along the outside of the transformer body, the driving mechanism 9 performs the first action, and the roller 602 rolls along the track rod 601 under the drive of the driving mechanism 9, thereby realizing the movement of the detection component 8.

[0029] like Figure 3 and Figure 4 As shown, the adjusting device 7 includes a reciprocating screw 701 and an adjusting block 702. The reciprocating screw 701 is vertically rotatably installed on the mounting seat 2 and connected to the driving mechanism 9. The adjusting block 702 is vertically slidably installed on the mounting seat 2 and cooperates with the reciprocating screw 701, and the detection component 8 is installed on the adjusting block 702.

[0030] It is understandable that when the driving mechanism 9 performs the second action, the reciprocating screw 701 will rotate under the action of the driving mechanism 9, and the reciprocating screw 701 acts on the adjustment block 702, and the adjustment block 702 can drive the detection component 8 to move up and down reciprocatingly.

[0031] like Figure 4 As shown, the driving mechanism 9 includes a driving device 901, a first transmission component 902 and a second transmission component 903. The driving device 901 is installed on the mounting seat 2. The input ends of the first transmission component 902 and the second transmission component 903 are connected to the output end of the driving device 901 for one-way transmission. The output end of the first transmission component 902 is connected to the roller 602, and the output end of the second transmission component 903 is connected to the reciprocating screw 701.

[0032] It can be understood that when the driving mechanism 9 performs the first action, the driving device 901 (forward rotation) can drive the roller 602 to rotate through the first transmission component 902, and the second transmission component 903 and the driving mechanism 9 will be disengaged, so that the detection component 8 remains stationary in the vertical direction. Similarly, when the driving mechanism 9 performs the second action, the driving device 901 (reverse rotation) can drive the reciprocating screw 701 to rotate through the second transmission component 903, and the first transmission component 902 and the driving mechanism 9 will be disengaged, so that the detection component 8 remains stationary in the horizontal direction.

[0033] It should be noted that the driving device 901 is common knowledge known to those skilled in the art, and can be a motor, a rotary cylinder or a rotary hydraulic cylinder, etc., and a motor is preferably used here. Moreover, the present application can realize the two functions of horizontal movement adjustment and vertical movement adjustment of the detection component 8 by using a driving device 901 in conjunction with a transmission component, reducing the use of a driving source, thereby reducing the weight of the entire device and making the installation more compact.

[0034] As a further description of the above technical solution: This application does not limit the specific structure of the first transmission assembly 902 and the second transmission assembly 903, and only provides a specific structure for reference below:

[0035] For the first transmission component 902 (such as Figure 4 and Figure 5 As shown): The first transmission component 902 includes a transmission belt 9022 and a pair of transmission wheels 9021, one transmission wheel 9021 is installed on the output end of the driving device 901 through a one-way bearing 10, and the other transmission wheel 9021 is installed on the rotating shaft on the roller 602, and the transmission belt 9022 is sleeved and installed on the outside of the transmission wheel 9021.

[0036] Specifically, when the driving device 901 rotates forward, the one-way bearing 10 on the transmission wheel 9021 is in an engaged state, and the driving device 901 can drive the roller 602 to rotate through the action of the transmission wheel 9021 and the transmission belt 9022; when the driving device 901 reverses, the one-way bearing 10 on the transmission wheel 9021 is in a free state, and the transmission wheel 9021 and the transmission belt 9022 are in a stationary state, that is, the first transmission component 902 is disengaged.

[0037] For the second transmission assembly 903 (such as Figure 4 and Figure 5 As shown): The second transmission assembly 903 includes a bevel gear 1 9031 and a bevel gear 2 9032. The bevel gear 1 9031 is installed on the output end of the driving device 901 through a one-way bearing 10. The bevel gear 2 9032 is installed on the reciprocating screw 701, and the bevel gear 1 9031 and the bevel gear 2 9032 are meshed.

[0038] Specifically, when the driving device 901 is reversed, the one-way bearing 10 on the bevel gear 1 9031 is in an engaged state, and the driving device 901 can drive the reciprocating screw 701 to rotate through the meshing action of the bevel gear 1 9031 and the bevel gear 2 9032; and when the driving device 901 is rotated forward, the one-way bearing 10 on the bevel gear 1 9031 is in a free state, and the bevel gear 1 9031 and the bevel gear 2 9032 are in a stationary state, that is, the second transmission component 903 is disengaged.

[0039] It should be noted that the first transmission assembly 902 can actually also adopt a chain transmission and a gear transmission method, and the second transmission assembly 903 can also adopt a worm gear transmission method.

[0040] One of the embodiments of the present application is as follows: Figure 1As shown, since the mounting base 2 can rotate horizontally and move vertically around the outside of the transformer body, if the driving device 901 is connected to a line, the line may be entangled. Therefore, the driving device 901 can be powered by a battery assembly 11 (battery). Therefore, a battery assembly 11 and a photovoltaic panel 12 can be installed on the top of the mounting base 2. The photovoltaic panel 12 can convert light energy into electrical energy and store it in the battery assembly 11, and then the battery assembly 11 can power the driving device 901.

[0041] Furthermore, the insulation of the transformer is also very important, so an electrically connected partial discharge insulation detection component 4 and an alarm device 5 can be installed on the enclosure 3, wherein the partial discharge insulation detection component 4 is connected and cooperated with the power transformer 1, and then the power transformer 1 is subjected to leakage detection.

[0042] Specifically, the partial discharge insulation detection component 4 includes a leakage detector, which can be connected to the transformer body shell. When the transformer body leaks, the leakage detector can detect the leakage signal, and then the alarm device 5 (such as an audible and visual alarm) can sound an alarm to remind the staff to deal with the leakage problem in time to ensure the normal operation of the transformer.

[0043] It should be further explained that the electrical control method used in the present application document is automatically controlled by a controller. The control circuit of the controller can be realized by simple programming by technicians in this field, which is common knowledge in the field. In addition, the present application document is mainly used to protect mechanical devices, so the present application document will no longer explain the control method and circuit connection in detail.

[0044] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought. The scope of protection claimed by the present application is defined by the attached claims and their equivalents.
