Description

Technical Field

[0001] The present invention relates to the field of industrial detection technology, and in particular to a chimney inner wall detection method and device system for unmanned high-altitude operations. Background Art

[0002] Industrial chimneys are vertical structures used in industrial facilities to discharge exhaust gases and smoke. Typically located atop factories or power plants, they are responsible for conveying harmful gases produced during combustion into the atmosphere to reduce their impact on the surrounding environment and human health. The corrosive nature of industrial chimneys in use makes regular inspections of their interior walls particularly important.

[0003] However, due to the high height of the chimney and the harsh working environment, the traditional inspection method generally involves transporting inspectors to the top of the chimney through a lifting device, and then using a manual hanging basket to enter the chimney for inspection. This high-altitude operation method not only poses huge safety hazards, but also has low inspection efficiency. Summary of the Invention

[0004] (1) Technical problems solved

[0005] In response to the shortcomings of the existing technology, the present invention provides a chimney inner wall detection method and device system for unmanned high-altitude operations, which solves the problems of high-altitude operations required for industrial chimney inner wall inspection, huge safety hazards, and low inspection efficiency.

[0006] (2) Technical solution

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a chimney inner wall detection method and device system for unmanned high-altitude operations, comprising a chimney body and a computer terminal, a blast heating air device fixedly connected to the right wall of the chimney body, and a detection component disposed inside the chimney body;

[0008] The detection component includes a helium balloon, a rope, a gateway box, a camera, an LED light, a fan housing, a filter, a connecting block, a micro motor, a fan blade body, a release rope, a fixing plate, a bracket, a top hole, a release roller and a main motor. The bottom of the helium balloon is fixedly connected to a rope, the bottom of the rope is fixedly connected to the gateway box, the bottom of the gateway box is fixedly connected to a camera and an LED light, the right side wall of the gateway box is fixedly connected to the fan housing, the front and rear side walls of the fan housing are fixedly connected to the filter, the interior of the fan housing is fixedly connected to a connecting block, there are two connecting blocks, and they are symmetrically distributed inside the fan housing, a micro motor is fixedly connected between the two connecting blocks, a fan blade body is provided in front of the micro motor, the output end of the micro motor is fixedly connected to the fan blade body, the top of the helium balloon is fixedly connected to the release rope, the top of the release rope is fixedly connected to the release roller, the bottom of the release roller is fixedly connected to the fixing plate, the circumferential surface of the fixing plate is fixedly connected to the bracket, the top of the fixing plate is provided with a top hole, and the top of the fixing plate is fixedly connected to the main motor.

[0009] Preferably, the gateway box is internally provided with a micro battery and a wireless internet bridge. The wireless internet bridge is connected to a computer terminal signal via wireless communication and is electrically connected to both the camera and the gyroscope sensor. The image information captured by the camera and the coordinate position of the gyroscope sensor are transmitted to the wireless internet bridge, which then transmits the information wirelessly to the computer terminal, which then displays the inner wall of the chimney.

[0010] Preferably, the ropes are provided in a plurality and evenly distributed below the helium balloon, and are made of high-temperature polyamide. High-temperature polyamide is a common high-temperature resistant nylon that has high rigidity, high strength, good dimensional accuracy and stability at high temperatures, as well as low warping and good chemical resistance. It is resistant to high temperatures and not easily deformed, making the helium balloon more stable.

[0011] Preferably, the gateway box, fan housing, filter, connection block, and fan blade body are all made of polymethacrylimide foam. Polymethacrylimide foam is a lightweight, high-strength, high- and low-temperature-resistant rigid foam material with high specific strength and stiffness, which can reduce the weight of the detection component.

[0012] Preferably, the output end of the main motor is fixedly connected to the release roller. When the main motor is started, the release roller rotates, thereby releasing the release rope, which cooperates with the helium balloon to facilitate the inspection of the inner wall of the chimney body from top to bottom.

[0013] Preferably, the release rope passes through the top hole from top to bottom, and a height mark is provided on the release rope for recording the height of the helium balloon. Different height marks indicate that the helium balloon is located at different heights.

[0014] Preferably, there are a plurality of brackets, which are evenly distributed on the fixing plate, and the brackets are clamped with the chimney body.

[0015] A method for detecting the inner wall of a chimney for unmanned high-altitude work, based on a chimney inner wall detection device system for unmanned high-altitude work according to any one of claims 1 to 8, is characterized in that it includes the following specific steps:

[0016] S1. Place the fixing plate on the top of the chimney body and connect the fixing plate and the chimney body through the bracket;

[0017] S2. Lower the helium balloon and start the main motor to rotate the release roller, thereby releasing more release ropes. As the release ropes are released, the helium balloon descends. The height mark on the release rope is used to record the defects observed by the camera at a certain height. With the help of the gyroscope sensor, the specific location of the current defect can be easily deduced.

[0018] S3. As the helium balloon is lowered, the camera captures the inner wall of the chimney and converts the information into electrical signals, which are then transmitted to the wireless Internet bridge. The wireless Internet bridge then transmits the information to the computer terminal via wireless communication, which converts the signals into visual images.

[0019] S4. During the inspection process, the computer terminal controls the activation of the micro motor through the wireless Internet bridge, which drives the fan blade body to rotate, thereby generating thrust on one side of the gateway box, which in turn drives the gateway box to rotate, thereby inspecting the inner wall of the chimney body;

[0020] S5. When necessary, start the heated blast air equipment to blow heated air into the chimney body. The helium balloon is lifted by its own force under the action of the hot air, and moves upward.

[0021] (3) Beneficial effects

[0023] 1. Personnel operate on the ground, significantly reducing the risk of personnel working at height;

[0024] 2. The equipment is simple and efficient, and can complete the inspection of the inner wall of a chimney hundreds of meters long in a short time;

[0028] 6. Good economy, which can save enterprises the costs related to high-altitude hanging baskets, safety measures, etc. BRIEF DESCRIPTION OF THE DRAWINGS
