Description

Technical Field

[0001] This utility model relates to the field of equipment status monitoring technology for hydropower station outgoing line plant, and in particular to an intelligent inspection system for hydropower station outgoing line plant based on visible light and infrared. Background Technology

[0002] As a critical link in the power system, the stable operation of equipment in the hydropower station's outgoing line depot directly affects the safety of the power grid and the reliable transmission of electricity. During routine inspections, the outgoing line depot of a hydropower station needs to focus on monitoring for issues such as overheating, damage, corrosion, cracks, poor contact, and electrical faults.

[0003] Traditional inspection methods primarily rely on manual inspection and video surveillance, typically using visible light imaging technology to monitor equipment status. However, traditional visible light monitoring systems are significantly less effective in low light, at night, or in adverse weather conditions, making it difficult to effectively detect subtle equipment faults or anomalies. Therefore, infrared thermal imaging technology has been introduced to detect temperature anomalies in equipment, such as overheating and malfunctions, which is particularly effective in low-light environments. However, some existing intelligent inspection systems generally acquire and use infrared images separately from visible light images, failing to efficiently integrate the two types of image data and limiting the comprehensiveness and accuracy of fault detection. Therefore, it is necessary to design an intelligent inspection system for hydropower station outgoing line depots based on visible light and infrared to address these issues. Summary of the Invention

It aims to solve the problems of low inspection efficiency and poor equipment adaptability of existing hydropower station outgoing line substation inspection devices. By setting up image acquisition equipment that combines visible light and infrared, and collecting environmental data in conjunction with it, the stability and reliability of the inspection device are improved, while meeting the needs of hydropower station outgoing line substation equipment inspection.

Detailed Implementation

[0018] Example 1: like Figure 1-2As shown, an intelligent inspection system for a hydropower station outgoing line based on visible light and infrared includes a base 3. An environmental sensor and a data acquisition device integrating a data transmission module 7 are connected to the upper surface of the base 3. The data acquisition device is integrated inside the housing 2. The bottom of the housing 2 is connected to the base 3. A camera module 1 is connected to the top of the housing 2. The camera module 1 includes a visible light camera 11 and an infrared thermal imaging camera 12.

[0019] Preferably, the environmental sensor includes a light sensor 4, a temperature sensor 5, and a humidity sensor 6.

[0020] Preferably, the data transmission module 7 includes a wireless communication module.

[0021] Preferably, the base 3 is connected to the housing via a rolling bearing, allowing the housing 2 to rotate horizontally.

[0022] Preferably, the camera module 1 is connected to the housing via a pitch pivot, allowing the camera module 1 to pitch and rotate.

[0023] Preferably, a shock-absorbing pad is provided between the base 3 and the housing 2.

[0024] Furthermore, the visible light camera 11 includes a lens, an adjustable aperture, a CMOS sensor, and an image processor; the infrared thermal imaging camera 12 includes a lens, an aperture, a CMOS sensor, and an image processor.

[0025] Preferably, the light sensor 4 is communicatively connected to the visible light camera 11 and is used to dynamically adjust the aperture size of the visible light camera according to the real-time light intensity.

[0026] Furthermore, the wireless communication module is used to transmit the processed data to the backend platform via the TLS / SSL protocol.

[0027] Preferably, the horizontally rotating rolling bearing and the pitch axis are both connected to remotely controllable servo motors to drive the camera module to achieve 360° panoramic scanning.

[0028] Furthermore, the bottom of the base 3 is provided with a detachable magnetic plate for magnetic attachment to the inspection vehicle or installation at a fixed inspection position.

[0029] Example 2: The intelligent inspection system for hydropower station outgoing line based on visible light and infrared proposed in this embodiment can be divided into two main parts in terms of overall function: data acquisition and mechanical control. The two parts work together to achieve all-weather, omnidirectional, and high-precision equipment status inspection.

[0030] The data acquisition section is centered around a visible light camera 11, an infrared thermal imaging camera 12, an environmental sensor, and a data transmission module 7. The visible light camera 11 and the infrared thermal imaging camera 12 are encapsulated in the camera module 1 at the top of the device, while the environmental sensor and the data transmission module are located in the middle of the device.

[0031] Visible light camera 11 is responsible for capturing visible defects such as texture, cracks, and corrosion on the surface of the equipment; infrared thermal imaging camera 12 simultaneously acquires heat distribution information within the same field of view, used to detect temperature anomalies such as overheating and poor contact. At the same time, light, temperature, and humidity sensors collect on-site environmental parameters in real time, providing a basis for adjusting the photosensitive parameters of camera module 1, initial image calibration of the calculation unit, and subsequent fault diagnosis.

[0032] The collected images and environmental data are securely transmitted back to the backend intelligent platform via a wireless communication module using the TLS / SSL protocol.

[0033] In terms of mechanical control, the top camera module 1 of this device can be tilted and rotated through the lower mechanism of the rotating shaft structure.

[0034] The central part of the device is an ellipsoidal shell 2 that integrates environmental sensors and data transmission modules. The shell 2 and the base 3 are connected by rolling bearings to achieve horizontal rotation. Both shafts are driven by remotely controllable servo motors, enabling the lens to complete 360° panoramic shooting on inspection platforms such as track robots or drones according to preset inspection programs.

[0035] A shock-absorbing pad is provided between the base 3 and the platform mounting surface to suppress mechanical vibration during movement and ensure clear images.

[0036] The entire casing is made of high-strength aluminum alloy and reinforced with IP65-rated sealing rings, ensuring reliable operation even in hydropower station environments characterized by high humidity, high salt spray, and strong electromagnetic interference. Once the device is online, maintenance personnel simply need to fix the standardized base into the slot of the adopted inspection platform, set the inspection program, and turn on the power. The system then autonomously completes the synchronous acquisition, real-time transmission, and fault warning of images and environmental data according to the preset program, significantly reducing the intensity of manual inspections and improving detection accuracy and response speed.
