Description

Technical Field

[0001] This utility model relates to the field of fire inspection technology, specifically to an intelligent fire inspection robot for main transformers in substations. Background Technology

[0002] The intelligent fire inspection robot for substation main transformers is an intelligent equipment integrating multiple modules. Designed for fire safety supervision scenarios of substation main transformers, it can replace manual inspection work. It uses infrared thermal imaging and temperature sensing modules to monitor potential fire hazards in real time, records fire hazards through high-definition camera equipment, and can automatically trigger audible and visual alarms or link with the background warning system. Equipped with fire-fighting equipment, it can quickly intervene and control the spread of fire when initial fire hazards or fires are detected.

[0003] In the prior art, patent publication number 202321604126.0 describes a fire inspection robot with an anti-corrosion protective cover, comprising a main body structure and an improved structure: the main body structure includes an inspection vehicle, a rotating shaft mounted on the top of the inspection vehicle, a mounting frame mounted on the top of the rotating shaft, two cameras symmetrically mounted on the top of the mounting frame, and a flat bottom end; the improved structure includes two half-shells, each half-shell having a through hole adapted to the camera on its front and a semi-circular hole on its bottom, the two semi-circular holes fitting together to form a circular hole with a diameter slightly larger than the rotating shaft. The two half-shells of this invention can fit together to form a protective shell for the mounting frame and the camera. The shell has a through hole on the front to expose the camera lens, and the circular hole at the bottom passes through the rotating shaft without interfering with it. Furthermore, the two half-shells are first engaged at the bottom by a locking mechanism, and then further secured at the top by a fixing mechanism, making the shell stable and less prone to detachment.

[0004] When a fire breaks out in a substation, the smoke generated can interfere with cameras, making it difficult for them to clearly capture the scene. This affects the accurate assessment of the fire's development and the status of critical equipment, hindering the precise formulation and adjustment of subsequent firefighting strategies. Furthermore, when the nozzles spray the fire, debris can fall onto the camera's surface, obstructing its field of view and reducing its image clarity. This can cause the camera to malfunction, preventing back-end monitoring personnel from obtaining real-time footage. Utility Model Content

[0005] To address the aforementioned shortcomings of existing technologies, this utility model provides an intelligent fire inspection robot for main transformers in substations. This robot effectively solves the problems in existing technologies where smoke generated during firefighting in substations interferes with cameras, making it difficult to clearly capture images of the scene. This hinders accurate judgment of fire development and the status of critical equipment, making it difficult to formulate and adjust subsequent firefighting strategies. Furthermore, the nozzles spraying fire can cause debris to fall onto the camera surface, obstructing the camera's field of view and reducing image clarity.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Example: An intelligent fire inspection robot for main transformers in substations, as shown in the attached document. Figure 1 - Appendix Figure 5 The system includes an inspection component 1, a robot body 11, a camera 12 fixed on the top of the robot body 11, a nozzle 13 fixed on the top of the robot body 11, and a track wheel 14 on one side of the robot body 11.

[0026] The robot body 11 is used to fix and install functional components such as camera 12 and nozzle 13, providing stable support for the collaborative work of each component. It is the main framework that ensures the robot can perform functions such as inspection and fire extinguishing. The camera 12 is used to capture images in the substation in real time, monitor the main transformer and the surrounding environment, assist in judging fire hazards and grasping the on-site situation during fire extinguishing. When a fire is detected, the nozzle 13 can spray the corresponding fire extinguishing medium to extinguish the fire in the main transformer and the surrounding fire area, and control the spread of the fire. The nozzle 13 is fixed with a mechanical arm for adjusting the angle and height. The tracked wheels 14 drive the robot body 11 to move by rotating, so that it can flexibly shuttle in the substation according to the preset route or as needed, and reach different locations to carry out inspection and fire extinguishing related work.

[0027] The observation component 2 is set on the robot body 11 and includes an observation piece 21. The observation piece 21 includes an exhaust box 211, which is fixed to the top of the robot body 11. A sweeping rod 212 is set on one side of the camera 12, and a filter screen 213 is sleeved on one end of the exhaust box 211.

[0028] When a fire occurs, the exhaust box 211 is activated to extract and discharge the smoke, reducing the smoke concentration and improving visibility at the scene. Activating the exhaust box 211 simultaneously moves the sweeping rod 212 back and forth on one side of the camera 12, clearing debris from its surface and preventing it from obstructing the camera's view. This ensures the camera can continuously and clearly capture images of the fire scene, guaranteeing smooth and efficient firefighting operations. The filter 213 has a porous structure; when smoke containing a large amount of particulate matter passes through, it is intercepted by the pores and cannot be discharged with the airflow, thus reducing the turbidity of the discharged smoke and minimizing pollution to the surrounding environment and equipment.

[0029] Specifically, the observation component 2 also includes a drive component 22, which includes a hinge rod 221. The hinge rod 221 is fixed to one end of the sweeping rod 212 and is rotatably connected to the top of the camera 12.

[0030] When the exhaust box 211 extracts smoke, it can cause the hinge rod 221 to rotate back and forth. The movement of the hinge rod 221 can drive the sweeping rod 212 to move back and forth on one side of the camera 12 to sweep away the debris that has fallen on it.

[0031] Furthermore, a turntable 222 is hinged to one side of the hinge rod 221, and a protective cover 223 is rotatably connected to the outside of the turntable 222. The protective cover 223 is fixed to the top of the camera 12.

[0032] The continuous rotation of turntable 222 can drive the hinge rod 221 to move back and forth, so that the sweeping rod 212 can clean the debris on the camera 12. The protective cover 223 is used to support turntable 222 and prevent turntable 222 from shifting.

[0033] Preferably, a first bevel gear 224 is fixed on one side of the turntable 222, and a second bevel gear 225 is provided on one side of the first bevel gear 224, and the first bevel gear 224 and the second bevel gear 225 mesh.

[0034] The second bevel gear 225 is rotatably connected to the protective cover 223 via a rotating shaft. The rotation of the second bevel gear 225 can drive the first bevel gear 224 to rotate, and the rotation of the first bevel gear 224 can drive the turntable 222 to rotate.

[0035] It should be noted that a first pulley 226 is fixed to one side of the second bevel gear 225, a first belt 227 is provided inside the first pulley 226, a second pulley 228 is provided at one end of the first belt 227, and a drive wheel 229 is fixed to one side of the second pulley 228.

[0036] The first belt 227 is rotatably connected to the inner wall of the protective cover 223 via a bearing, and the second pulley 228 is rotatably connected to the protective cover 223. The first belt 227 is movably connected to the protective cover 223. When the exhaust box 211 extracts smoke, it can rotate the drive wheel 229. There are blades on the drive wheel 229, and the wind force generated can make the drive wheel 229 rotate. The rotation of the drive wheel 229 can drive the second pulley 228 to rotate, and the second pulley 228 drives the first belt 227 to rotate. The rotation of the first belt 227 drives the first pulley 226 to rotate, and then the rotation of the first pulley 226 can drive the second bevel gear 225 to rotate.

[0037] Furthermore, the observation component 2 also includes a rotating component 23, which includes an impeller 231 disposed inside the exhaust box 211.

[0038] When the impeller 231 rotates at high speed inside the exhaust box 211, its blades cut and agitate the smoke entering the exhaust box 211. When the smoke enters the exhaust box 211 with the airflow and comes into contact with the blades of the impeller 231, the smoke cloud that has gathered together will be divided into many smaller parts, thereby achieving the initial dispersal of the smoke. The impeller 231 rotates at high speed under the drive of the motor, creating a negative pressure environment inside the exhaust box 211. At this time, the air carrying smoke can be drawn into the exhaust box 211 under the action of pressure difference, thereby realizing the function of extracting smoke from the fire scene, which will help reduce the smoke concentration, improve the visibility at the scene, and ensure that the camera 12 can clearly capture the image.

[0039] Specifically, a filter pad 232 is fixed to one side of the filter screen 213. The filter pad 232 is made of activated carbon.

[0040] During the extraction of smoke by the exhaust box 211, in addition to visible particulate matter, the smoke also contains harmful gases. Activated carbon, with its well-developed pore structure and large specific surface area, allows harmful gas molecules to adhere to the pores of the activated carbon, thereby effectively adsorbing harmful gases in the smoke, reducing the content of harmful components in the exhaust smoke, and minimizing harm to the surrounding environment and the health of on-site personnel.

[0041] Preferably, an atomizing head 233 is fixed to the top of the exhaust box 211, and a water tank 234 is fixed to the top of the atomizing head 233.

[0042] When the exhaust box 211 extracts smoke, the water in the water tank 234 is delivered to the atomizing head 233. The atomizing head 233 converts the water into tiny water mist particles and sprays them out. These particles mix thoroughly with the smoke drawn into the exhaust box 211, using the water mist to absorb some fine particulate matter in the smoke, increasing its weight and making it easier for it to be intercepted and filtered by the filter screen 213. This further improves the purification effect of the smoke and reduces the turbidity of the emitted smoke. The water tank 234 stores water to continuously supply the atomizing head 233 with the water needed to generate water mist. This ensures that the atomizing head 233 has sufficient water for atomization during the operation of the exhaust box 211, meeting the needs of smoke purification and cooling. The water tank 234 has a water inlet on top for easy water addition by the user.

[0043] A fan is fixedly connected to the output end of the motor, and the motor is connected to the water tank 234 via a connecting pipe. When the motor is running, it drives the fan to rotate and generate airflow. This airflow acts on the water in the water tank 234. Driven by the airflow, the water flows along the atomizing head 233 connected to the water tank 234, and then uses the airflow generated by the rotation of the motor to achieve water spraying.

[0044] When in use, the robot body 11 is first started. The track wheels 14 rotate to move the robot body 11 to the inspection area of ​​the main transformer in the substation. The camera 12 can capture the scene in real time and monitor the status of the main transformer. If a fire is detected, the robotic arm adjusts the angle and height of the nozzle 13. The nozzle 13 sprays fire extinguishing medium to carry out fire extinguishing operations. At the same time, the exhaust box 211 is started. The motor drives the impeller 231 to rotate at high speed in the exhaust box 211, forming a negative pressure to extract the smoke at the fire scene. The smoke is purified by the filter screen 213 and the activated carbon filter pad 232 before being discharged, reducing the smoke concentration at the scene, improving visibility, and avoiding smoke interference with the imaging of the camera 12.

[0045] When the exhaust box 211 is working, the airflow drives the drive wheel 229, causing the blades to rotate under force. The drive wheel 229 drives the second pulley 228 to rotate. The second pulley 228 drives the first pulley 226 to rotate via the first belt 227. The first pulley 226 drives the second bevel gear 225 to rotate. The second bevel gear 225 meshes with and drives the first bevel gear 224 to rotate. The first bevel gear 224 drives the turntable 222 to rotate along the protective cover 223. The turntable 222 drives the hinge rod 221 to rotate back and forth. The hinge rod 221 can then drive the sweeping rod 212 to move back and forth on one side of the camera 12 to sweep away debris on the surface of the camera 12, prevent obstruction of the field of view, and ensure that the camera 12 clearly captures the fire spread trajectory and equipment status, providing accurate image support for the background monitoring personnel to formulate and adjust the fire extinguishing strategy.

[0046] During the firefighting process, water tank 234 supplies water to atomizing head 233, which sprays water mist. The water mist mixes with the smoke drawn in by exhaust box 211, adsorbing fine particulate matter and improving the smoke purification effect. After the fire is extinguished, exhaust box 211 and atomizing head 233 are turned off, and track wheels 14 drive robot body 11 to move to the next inspection point. Camera 12 continues to monitor, ensuring that the inspection and firefighting operations are carried out efficiently and safely throughout the process, and improving the fire safety supervision capability of the substation's main transformer.

[0047] In summary, the system can extract smoke and simultaneously remove debris from the surface of camera 12, quickly reducing the smoke concentration at the fire scene. This allows camera 12 to clearly capture images such as the fire's spread trajectory, helping back-end monitoring personnel accurately assess the fire situation and adjust firefighting strategies in a timely manner. By removing debris, camera 12 is prevented from being obstructed, ensuring its continuous and stable operation and allowing monitoring personnel to monitor the firefighting effect in real time. At the same time, it provides clear visual support for the robot's own movement and the operation of firefighting equipment, improving firefighting efficiency and ensuring the safe and orderly progress of firefighting and rescue work.
