[0036] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0037] like Figure 1 As shown, the noise reduction dry-type transformer provided in this embodiment includes a dry-type transformer body 1 and a monitoring device 6 arranged outside the dry-type transformer body 1. A shock-absorbing pad 2 is provided below the dry-type transformer body 1, and a noise reduction protective shell 3 for shielding and protecting the dry-type transformer body 1 is fixedly installed on the outside of the shock-absorbing pad 2; by installing the shock-absorbing pad 2, the direct connection between the dry-type transformer body 1 and the ground is cut off, which can effectively reduce the propagation of sound waves through the ground, and the noise reduction protective shell 3 is provided on the outside of the dry-type transformer body 1, which can effectively isolate the noise generated by the dry-type transformer body 1 and reduce the impact of the noise on the surrounding environment.

[0038] Furthermore, sound-absorbing cotton is installed inside the noise-reducing protective housing 3, further enhancing the sound insulation of the dry-type transformer body 1. Monitoring equipment 6, consisting of a high-definition camera and a temperature and humidity sensor, not only provides all-around, multi-angle monitoring of the transformer, ensuring comprehensive coverage and timely detection of external abnormalities, but also utilizes advanced technologies such as high-definition cameras to clearly capture details of the transformer's exterior, such as cracks, rust, and oil leaks, improving monitoring accuracy. Furthermore, the temperature and humidity sensor further monitors the dry-type transformer body 1.

[0039] It should be noted that monitoring device 6 is equipped with a remote control module that supports remote management. Monitoring device 6 supports remote access and control, allowing operators to remotely view real-time images and data of the transformer over the network, enabling remote monitoring and management. Furthermore, monitoring device 6 can be flexibly configured and adjusted based on actual needs, such as adjusting camera angles and setting inspection routes, to accommodate diverse monitoring requirements. Monitoring device 6 can also analyze and compile collected data, generating inspection reports and maintenance recommendations to support operational decision-making. Data analysis can promptly identify operational trends and potential issues within the dry-type transformer 1, providing a scientific basis for preventative maintenance.

[0040] In order to achieve efficient monitoring of the dry-type transformer body 1, in this embodiment, as shown in FIG. Figure 2 - Figure 6As shown, a walking mechanism 5 for moving the monitoring device 6 and a bottom guide seat 4 for cooperating with the monitoring device 6 are provided in the noise reduction protective shell 3, the walking mechanism 5 includes a base 501, a driving structure 502 installed on the upper surface of the base 501 and a top guide seat 503 arranged above the bottom guide seat 4, the driving structure 502 includes a driving motor 5021 installed on the upper surface of the base 501 by bolts, a rotating shaft 5022 fixedly installed on the output shaft of the driving motor 5021, a connecting shaft 5023 fixedly installed at the other end of the rotating shaft 5022, and a walking wheel 5024 rotatably installed at the other end of the connecting shaft 5023; wherein, there are two rotating shafts 5022 and two walking wheels 5024, and the two rotating shafts 5022 are provided with a transmission structure, a second guide groove 504 for cooperating with the walking wheel 5024 is opened in the top guide seat 503, and the walking wheel 5024 extends into the second guide groove 504 and is rollingly connected to its inner wall to realize the circular motion of the monitoring device 6.

[0041] When this embodiment is in use, the circular motion of the walking mechanism 5 enables the monitoring device 6 to rotate around the dry-type transformer body 1, thereby performing all-round and multi-angle monitoring of the dry-type transformer body 1, ensuring no blind spot coverage, timely discovering abnormal conditions outside the dry-type transformer body 1, realizing unmanned automated inspection, and reducing the workload of operation and maintenance personnel. In addition, the monitoring device 6 that can move around can replace manual inspections, reducing the safety risks of staff, thereby achieving the advantages of efficiency and convenience.

[0042] Specifically, such as Figure 3 and Figure 4 As shown, both the bottom guide seat 4 and the top guide seat 503 have outward-connecting through-holes 505. The dry-type transformer body 1 extends through the through-holes 505 into the bottom guide seat 4. The bottom transmission structure consists of two first synchronous pulleys 5025, connected by a first synchronous belt 5026. The two first synchronous pulleys 5025 are fixedly mounted on the exterior of two connecting shafts 5023. When the drive motor 5021 is activated, the drive shafts 5023 transmit power, causing the running wheels 5024 to rotate, driving the base 501 in a circular motion around the bottom guide seat 4.

[0043] It should be noted that the bottom guide seat 4 and the top guide seat 503 are annular in shape, and a first guide groove 42 is formed inside the bottom guide seat 4. A slider 5011 is fixedly mounted on the outside of the base 501 and slidably engages with the first guide groove 42. To improve the movement effect, the outer surface of the running wheel 5024 is sleeved with an anti-slip pad to enhance the rolling connection with the second guide groove 504. In addition, a weight block is provided on the slider 5011 to prevent excessive force on the end of the base 501. A running wheel 5024 can also be added to the slider 5011 and connected to the connecting shaft 5023 via a synchronous belt.

[0044] The bottom of the bottom guide seat 4 is welded with support legs 41 fixed to the upper surface of the shock-absorbing pad 2. There are at least three support legs 41, providing stable support for the bottom guide seat 4. Two symmetrical support seats 5027 are welded to the upper surface of the base 501. Two rotating shafts 5022 and a connecting shaft 5023 are respectively connected to the bearings of the two support seats 5027.

[0045] In order to further improve the monitoring effect of the monitoring device 6, in this embodiment, as Figure 2 、 Figure 5 - Figure 8 As shown, a reciprocating mechanism 7 is provided on the upper surface of the base 501 for use in conjunction with the traveling mechanism 5 to adjust the monitoring device 6. The reciprocating mechanism 7 includes a synchronization shaft 701 and a telescopic structure 704 disposed on the outside of the base 501, a turntable 702 fixedly mounted on one end of the synchronization shaft 701, a connecting rod 703 disposed on the outside of the turntable 702 and connected to the telescopic structure 704, and a synchronization structure 706 mounted on the other end of the synchronization shaft 701 and connected to the rotating shaft 5022. The synchronization structure 706 is composed of two second synchronization wheels 7061, and a second synchronization belt 7062 is connected between the two second synchronization wheels 7061. The two second synchronization wheels 7061 are respectively mounted on the synchronization shaft 701 and the rotating shaft 5022.

[0046] When in use, this embodiment further improves the monitoring capability of the monitoring device 6 on the dry-type transformer body 1 by performing circular motion of the monitoring device 6 and then adjusting the reciprocating mechanism 7 up and down. Furthermore, the coordinated use of the traveling mechanism 5 and the reciprocating mechanism 7 can enhance the flexibility and comprehensiveness of monitoring. For example, through the circular motion of the traveling mechanism 5, the monitoring device 6 can perform all-around monitoring around the dry-type transformer body 1, ensuring coverage without blind spots. At the same time, the up and down adjustment function enables the monitoring device 6 to perform precise monitoring at different heights and angles of the transformer, capturing more details. Different monitoring tasks may require attention to different parts or angles of the dry-type transformer body 1. This design enables the monitoring device 6 to flexibly adjust the monitoring position and angle to meet diverse monitoring needs.

[0047] Furthermore, the up and down adjustment function enables monitoring device 6 to precisely locate key areas requiring monitoring, such as the air inlet and outlet, wiring terminals, and other key locations of the dry-type transformer body 1, thereby improving monitoring accuracy. Automated adjustment and monitoring reduce the repetitive labor of manual inspections. The coordinated use of the traveling mechanism 5 and the reciprocating mechanism 7 improves monitoring efficiency and accuracy. Furthermore, automated adjustment and monitoring reduce the repetitive labor of manual inspections and improve monitoring efficiency. Automated monitoring also enables continuous and uninterrupted monitoring, enabling the timely detection of potential problems.

[0048] Specifically, the telescopic structure 704 consists of a telescopic sleeve 7041 and a telescopic rod 7042, which are telescopically connected. A buffer spring 705 is installed on the outside of the telescopic rod 7042. A mounting platform 707 is welded to the side wall of the base 501, and the bottom ends of the telescopic rod 7042 and the buffer spring 705 are both mounted on the upper surface of the mounting platform 707. By installing the buffer spring 705 on the outside of the telescopic rod 7042, the telescopic structure 704 can be cushioned during expansion and contraction, improving the reciprocating adjustment of the monitoring device 6 by the reciprocating mechanism 7 and ensuring stable operation. The bottom end of the telescopic sleeve 7041 is welded with an abutment block 7045 connected to the top end of the buffer spring 705. The outer surface of the telescopic sleeve 7041 is plugged and mounted with a mounting sleeve 7043. The abutment block 7045 is a circular rubber pad.

[0049] In order to ensure the stable expansion and contraction of the telescopic structure 704, Figure 7 and Figure 8 As shown, two symmetrically positioned stoppers 7046 are fixedly mounted on the outer surface of the top end of the telescopic rod 7042. The telescopic sleeve 7041 is hollow and has a stopper slot 7047 that slidably engages with the two stoppers 7046. A mounting plate 7044 for the monitoring device 6 is welded to the top end of the telescopic sleeve 7041. The monitoring device 6 is bolted to the top surface of the mounting plate 7044. The telescopic rod 7042 is limited and guided by the sliding engagement between the stoppers 7046 and the stopper slots 7047, thereby achieving linear displacement.

[0050] In this embodiment, a vertical seat 708 is welded to the upper surface of the base 501, and the synchronization shaft 701 is connected to the vertical seat 708 bearing to ensure stable rotation of the synchronization shaft 701 and achieve stable adjustment. Both ends of the connecting rod 703 are rotatably installed with shafts, and the two shafts are respectively connected and fixed to the turntable 702 and the mounting sleeve 7043.

[0051] like Figure 1 - Figure 8 As shown, the principle of the noise reduction dry-type transformer provided in this embodiment is as follows:

[0052] During use, the drive motor 5021 is started and transmitted through the connecting shaft 5023, so that the walking wheel 5024 rotates and drives the base 501 to move in a circle around the bottom guide seat 4. At the same time, the transmission of the synchronous structure 706 is used to drive the turntable 702 to rotate, and the telescopic structure 704 is driven to reciprocate through the connecting rod 703, thereby adjusting the monitoring device 6 up and down, so that all-round and multi-angle monitoring can be carried out around the dry-type transformer body 1, ensuring coverage without blind spots and timely detecting abnormal conditions outside the dry-type transformer body 1.

[0053] The foregoing description shows and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments.
