Abstract
Description
Technical Field
[0001] This application relates to the field of intelligent inspection technology for power systems, specifically to a voiceprint and function expansion module and an inspection device. Background Technology
[0002] During operation, power systems may emit abnormal ultrasonic signals due to equipment failure, abnormal vibration, partial discharge, etc. Acoustic fingerprint devices utilize this principle to detect and locate power system faults by collecting abnormal ultrasonic signals and processing them through a processor unit. This helps prevent major accidents from occurring.
[0003] Traditional voiceprint devices usually require manual hand-holding or installation on the monitored device. Manual hand-holding makes it difficult to repeatedly locate the same monitored object in actual operation; while fixed installation increases the cost of using the voiceprint device as the number of monitored devices increases.
[0004] In recent years, legged robots have been widely used in intelligent inspection of power systems. Compared with wheeled robots, they have stronger adaptability to road conditions and greater self-adjustment capabilities. Most of the functional equipment carried by legged robots is transplanted from wheeled robots. However, this functional equipment does not fully utilize the flexibility and adjustability of the legged robot itself, often featuring complex power and transmission components, resulting in large size and complex structure. Furthermore, as the functions of legged robots increase, the number of functional equipment required also gradually increases, such as robotic arms and detectors. This leads to a gradual decrease in the number of external interfaces that the robot body can provide, increasing the hardware burden on the robot and limiting the expansion of its functions.
[0005] Therefore, there is an urgent need for an inspection robot equipped with voiceprint and functional expansion modules to solve the above problems. Utility Model Content
[0006] To address the shortcomings of existing technologies, this application provides a voiceprint and function expansion module for inspection robots, which solves the problems existing in the current voiceprint devices and business function expansion of inspection robots.

[0017] Preferably, the first support and the first outer shell are mated together to form a first cavity, and the acoustic text component is located in the first cavity;
[0018] The second support and the second outer shell are connected to each other to form a second cavity, and the functional expansion component is located in the second cavity; the external interface is located on the surface of the second cavity.
[0019] Preferably, a first sealing element is provided between the first support portion and the first housing.
[0020] A second sealing element is provided between the second support and the second housing;
[0021] The external interface is equipped with a third sealing element.
[0022] Preferably, the voiceprint and function expansion module is provided with a protective cover.
[0023] Preferably, the voiceprint component includes: a microphone array board, an image acquisition module, and a processor unit;
[0024] The microphone array plate is attached to the inner wall of the first housing, which has microphone holes;
[0025] The image acquisition module records images through an image acquisition hole;
[0026] The high-power chip in the processor unit is attached to the first support, and the gap between them is filled with thermally conductive material.
[0027] Preferably, the high-power chip of the functional expansion component is attached to the second support portion, and the gap between the two is filled with thermally conductive material.
[0028] Preferably, when the functional expansion component is a wireless communication module, an antenna is installed on the external interface.
[0029] The second aspect of this application discloses an inspection device, including a legged robot body and the aforementioned voiceprint and function extension module, wherein the voiceprint and function extension module is mounted on the legged robot body.
[0030] Compared with the prior art, the beneficial effects of this application include at least the following:

[0033] Through multiple external interfaces and functional expansion components of the voiceprint and function expansion modules, the number of interfaces on the robot body can be further increased, enhancing the expandability of the robot body's business function devices. When functional devices are installed, they are directly connected to the voiceprint and function expansion modules without needing to be connected to the robot body, improving the convenience of assembling and disassembling the robot's business function devices; at the same time, decoupling the robot body from the business function devices avoids crosstalk between the body and the devices.
