1. KT-985 CCTV Pipeline Inspection Robot Product Overview

The KT-985 is a CCTV pipeline inspection robot used for remote visual inspection inside underground pipelines. The system consists of a front and rear HD camera crawler, an automatic/manual cable reel, and a wireless tablet control terminal.

The robot travels inside the pipeline via a dual-motor, six-wheel drive system, with a maximum output power of 200W. It supports three-speed adjustment, forward/reverse constant-speed cruise, and in-place turning. The maximum climbing angle is 45°. With 4-inch, 6-inch, and 8-inch wheel sets and a 170 mm electric lifting frame, it adapts to on-site inspection tasks in different pipe diameters.

The camera system uses a front 2.1-megapixel HD camera and a rear 5-megapixel starlight-level HD camera. The front camera system supports 10× optical zoom and 16× digital zoom. The gimbal provides 360° axial rotation and 180° pitch observation, allowing operators to inspect the inner pipe wall from different directions.

For data management, the KT-985 is equipped with a self-developed host computer control system and municipal underground pipeline defect interpretation software, supporting video management, defect recording, project pipeline and defect sketch management, and inspection report export.

2. KT-985 Core Structure and Main Functions

2.1 Dual-Motor Six-Wheel Drive Crawler

The KT-985 CCTV pipeline inspection robot uses a dual-motor, six-wheel drive structure with a maximum output power of 200W.

The equipment supports forward, reverse, steering, and in-place turning, and features three-speed adjustment and forward/reverse constant-speed cruise. Operators can adjust robot travel speed based on pipeline length, slope, and internal environment.

Main parameters:

45° is the product’s maximum climbing angle. Actual passage capability is also affected by pipeline bottom friction, mud, water accumulation, cable drag force, wheel configuration, and obstacles.

2.2 Front and Rear Dual HD Camera Systems

The KT-985 is equipped with two camera systems, respectively responsible for forward inspection observation and rear auxiliary observation.

Front camera:

• 2.1-megapixel HD imaging
• Image resolution: 1920×1080
• Supports 10× optical zoom
• Supports 16× digital zoom
• Auto focus and manual focus
• Works with a 360° rotating gimbal for multi-angle observation

Rear camera:

• 5-megapixel
• Starlight-level HD imaging
• Minimum illumination: 0.001 lux
• Used to observe the environment behind the robot and assist equipment recovery

Both front and rear camera systems can record images during inspection. When operators identify suspected cracks, damage, abnormal joints, or foreign objects, they can save videos and photos via the tablet control terminal.

Note: The front and rear cameras have different pixel and functional configurations. The two camera systems should not be understood as having the same resolution.

2.3 360° Rotating Gimbal and 180° Pitch Observation

The KT-985 front camera system is equipped with an electric gimbal supporting:

• 360° axial rotation
• 180° pitch, i.e., ±90° up and down
• 10× optical zoom
• 16× digital zoom
• Auto/manual focus

During pipeline inspection, operators can adjust the camera angle based on the target position to observe the pipeline top, bottom, side walls, and joint areas.

When an abnormal location is found, the robot can be paused, the gimbal direction and focus adjusted, and the suspected defect observed and recorded in detail.

2.4 Starlight-Level Low-Light Imaging and LED Lighting

Underground drainage pipelines typically have no natural light, so the camera system must rely on its own lighting for image acquisition.

The KT-985 is equipped with three LED lighting groups: far light, near light, and tail light.

The rear camera uses starlight-level low-light imaging technology, with a minimum illumination parameter of 0.001 lux. Combined with multiple LED lighting groups, it improves observation conditions in underground environments without natural light.

The camera system also supports auto focus, manual focus, and electric heating defogging, reducing the impact of lens fogging in humid environments.

Note: Low-light imaging and lighting systems primarily improve observation capability in dark environments. If the water inside the pipeline is turbid, mud covers the lens, or the pipe wall is obscured by deposits, on-site conditions still need to be addressed first.

2.5 170 mm Electric Lifting Frame

The KT-985 is equipped with an electric lifting structure with a maximum lifting height of 170 mm.

Operators can adjust the lifting frame height via the wireless tablet control terminal so that the camera is positioned at a relatively suitable observation position in pipelines of different diameters.

The electric lifting structure, used together with multiple wheel specifications, improves the robot’s adaptability to different pipeline sizes.

2.6 4-Inch, 6-Inch, and 8-Inch Multi-Specification Wheels

The KT-985 is equipped with three specifications of rubber wheels:

Operators can select the corresponding wheel set based on the target pipeline inner diameter and site conditions, then adjust robot height with the electric lifting frame.

The equipment’s nominal applicable pipe diameter is DN200–2000 mm. During procurement, it is recommended to provide the actual inner diameter of the target pipeline, pipeline shape, and manhole dimensions so that technical personnel can confirm the wheel set and lifting configuration.

2.7 IP68 Waterproof Design

The KT-985 crawler and camera system use IP68 protection design.

• Crawler nominal waterproof pressure: 2.5 bar
• Nominal applicable water depth: 10 m
• Crawler operating temperature: -20°C to 55°C
• Camera system operating temperature: -30°C to 60°C

Protection rating and nominal water depth parameters should be understood in combination with specific components and actual operating conditions. Before procurement, it is recommended to confirm protection test conditions, applicable component scope, and on-site water depth requirements.

3. Long-Distance Inspection Cable and Metering System

3.1 100 m Standard Cable, Up to 500 m Customized

The KT-985 comes standard with a 100 m inspection cable, customizable according to project requirements, with a maximum support of 500 m.

Cable length selection should consider actual inspection distance, equipment placement position, manhole location, and pipeline routing. The nominal tensile load should not be directly used as the safe working tension for daily operations. Actual use should follow equipment operating requirements.

3.2 ±0.01 m High-Precision Metering System

The KT-985 cable reel is equipped with an encoder metering system with a metering accuracy of ±0.01 m.

During inspection, the system can display the robot’s distance into the pipeline in real time. When a suspected defect is found, operators can record the abnormal location based on current metering data, video, and photos.

The metering system helps operators record inspection distance and provides reference for subsequent repair, re-inspection, and on-site locating.

Note: Metering accuracy does not equal actual defect positioning error. Cable slack, bends, slipping, starting point settings, and metering calibration may all affect on-site positioning results.
