[0012] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0013] An elliptical ring adsorption climbing composite robot, the composite robot is composed of an elliptical ring adsorption climbing device and a multifunctional robot. Figure 1 As shown, the composite robot mainly includes: a frame structure, an adsorption unit, a hydraulic unit, a track unit and a multifunctional robot; the frame structure adopts an upper and lower two-layer frame structure, wherein the track unit is arranged on the top of the frame structure, and the multifunctional robot is arranged on the track unit, so that the multifunctional robot moves on the track unit; the adsorption unit is arranged on the frame structure, and the hydraulic unit is respectively connected to the upper and lower layers of the frame structure, and the distance between the upper structure and the lower structure in the frame structure is controlled according to the hydraulic unit.

[0014] In this embodiment, the composite robot mainly includes a vacuum suction cup 1, a multifunctional robot 2, a ring track 3 and a hydraulic system 4. In this embodiment, the elliptical ring adsorption climbing device of the composite robot adopts a unique elliptical ring frame design, which can adapt to various curved surfaces and shapes. The device consists of an upper and lower elliptical ring frame, which is connected by a hydraulic rod to form a stable support structure. The adsorption unit is equipped with multiple vacuum suction cups and a spring buffer system, which can adapt to curved surfaces of different sizes and shapes to ensure a uniform and stable adsorption effect.

[0015] The elliptical ring adsorption climbing composite robot adopts an elliptical structure: the elliptical track and frame design, due to its geometric characteristics, has stronger surface adaptability and force optimization capabilities; through the evenly distributed support points and adsorption units to provide stable support, the robot can still maintain rigidity and adsorption effect on complex surfaces. In addition, the elliptical frame has evenly distributed force, effectively reducing the risks caused by local stress concentration, and at the same time, in conjunction with the track system, it provides a closed and efficient moving path to achieve flexible movement in a curved three-dimensional space.

[0016] The frame structure is made of lightweight, high-strength materials to reduce weight and increase stability.

[0017] The adsorption unit includes a spring buffer system and a plurality of vacuum suction cups, and each vacuum suction cup is evenly distributed on the side of the frame structure; the spring buffer system is arranged inside the frame structure and connected to the vacuum suction cup for adjusting the pressure of the vacuum suction cup.

[0018] The number and distribution of vacuum cups are optimized according to the shape and size of the surface to be adsorbed to ensure uniform and stable adsorption effect.

[0019] The hydraulic unit includes a hydraulic rod and a hydraulic system; the hydraulic rod connects the upper and lower frames; the hydraulic system is used to control the lifting and lowering movement of the hydraulic rod. The hydraulic system includes a hydraulic pump, an oil tank, a control valve and a hydraulic cylinder. The hydraulic rod accurately controls the relative movement of the upper and lower frames, thereby achieving height adjustment of the system.

[0020] The track unit is used to carry the multifunctional robot. It is of adjustable design and can be adjusted according to the size of the multifunctional robot or other monitoring equipment to ensure the stable operation of the equipment.

[0021] The multifunctional robot is equipped with detection equipment and exchanges data with the external control system through the wireless communication module to achieve remote control and monitoring.

[0022] like Figure 3 As shown, the multifunctional robot is provided with buckles and rollers. The buckles are provided on the sides of the multifunctional robot for fixing the multifunctional robot on the track unit; the rollers are provided at the position where the multifunctional robot contacts the track unit so that the multifunctional robot slides on the track unit.

[0023] The device also includes a sensor module for detecting the position, posture and state of the adsorption unit of the device to ensure the stability and safety of the device.

[0024] The device also includes a power module to provide sufficient power support for the adsorption unit, the hydraulic unit, the track unit and the multifunctional robot.

[0025] The device is also equipped with an emergency stop button and a safety locking mechanism to ensure the safety of operators in abnormal situations.

[0026] The robot uses the adsorption unit as the core climbing structure, and multiple vacuum suction cups are evenly distributed on the side of the frame to achieve firm adsorption of surfaces of various materials and shapes. The vacuum pump generates negative pressure, which gives the suction cup a strong adsorption force, and the spring buffer system is connected between the suction cup and the frame, which can dynamically adjust the pressure of the suction cup according to the shape of the surface. Specific process: The spring buffer system is connected to the vacuum suction cup and can dynamically adjust the pressure of the suction cup according to the shape change of the adsorption surface. When the robot is adsorbed on an irregular surface, the spring in the system will automatically compress or stretch according to the height or inclination of the surface, adjust the pressure of the suction cup, and make adaptive adjustments according to the influencing factors to ensure that each suction cup maintains uniform and stable contact with the surface, avoiding uneven adsorption force or sliding caused by uneven surface. This design effectively enhances the robot's adaptability to irregular surfaces, ensures a stable and reliable adsorption process, and prevents sliding or falling off.

[0027] The factors affecting the adaptability of the spring buffer system include:

[0028] Surface shape and curvature: Surface irregularities, bumps or depressions, and changes in curvature directly affect the contact of the suction cup. Different surface curvatures require the spring buffer system to adjust the pressure of the suction cup according to the height changes in different areas to ensure the suction effect.

[0029] Surface material and friction: The material of the surface (such as metal, glass, plastic, etc.) will affect the friction between the suction cup and the surface. Smoother or polished surfaces may require more precise pressure adjustment, while rough or textured surfaces may affect the contact stability of the suction cup and cause uneven pressure distribution.

[0030] Number and distribution of suction cups: The number, position and distribution of suction cups have an important influence on the uniformity of pressure. On complex or irregular surfaces, the distribution of suction cups needs to be optimized according to the shape of the curved surface to ensure balanced pressure. If the suction cups are not arranged properly, even with a spring buffer system, it may lead to insufficient suction force or overload.

[0031] External environmental factors: Environmental factors such as temperature, humidity, and air pressure may also affect the working efficiency of the spring buffer system. For example, a low temperature environment may cause the spring hardness to change, thereby affecting the sensitivity of the pressure regulation.

[0032] Load and suction force changes: During the robot suction process, the suction cup may encounter changes in external loads, such as the weight of the object or friction. The change in load will affect the demand for suction force, and the spring buffer system needs to dynamically adjust the contact pressure of the suction cup according to the load change.

[0033] As a key component in the climbing process, the hydraulic unit connects the upper and lower frames and achieves precise height and angle adjustment through hydraulic rods. During the climbing process, the hydraulic rods push the frames to complete relative movement and gradually adjust the position of the adsorption points, thereby achieving "step-by-step" climbing. The high flexibility of the hydraulic system enables the robot to cope with target surfaces of different curvatures and height changes, ensuring the smoothness and stability of the climbing action.

[0034] The track unit provides support for the multifunctional subsystems inside the robot and indirectly assists the climbing process. Its ring structure optimizes the distribution of force, ensuring that the robot is evenly stressed as a whole, while providing a stable movement path for the multifunctional robot, facilitating precise operation and maintenance tasks on complex surfaces.

[0035] The sensor module runs through the entire climbing process, providing real-time monitoring of the robot's position, posture, and adsorption status. The system automatically adjusts the adsorption point and the action of the hydraulic unit through sensor feedback to ensure the safety and accuracy of climbing. When insufficient adsorption force or abnormal posture is detected, the robot can quickly make adjustments to avoid falling accidents, thereby achieving efficient operation in complex environments.

[0036] During the operation, the number and distribution of vacuum cups are first optimized according to the size and shape of the irregular curved surface objects to be inspected and maintained at high altitudes. Then, the vacuum pump is started to firmly attach the cups to the surface, and the height of the device is adjusted using the hydraulic rod to achieve a suitable working position. The track system is located at the top of the device and is used to carry multifunctional robots and monitoring equipment. It exchanges data with the external control system through the wireless communication module to achieve remote control and monitoring.

[0037] In order to ensure the stability and safety of the elliptical ring adsorption climbing device, the device is equipped with a sensor module to detect the position, posture and status of the adsorption unit of the device, and is provided with an emergency stop button and a safety locking mechanism to ensure the safety of the operator under abnormal circumstances.

[0038] When facing irregular surfaces, the elliptical ring adsorption climbing composite robot ensures stability and efficient operation through a number of key designs. The adsorption unit is an important component, equipped with multiple evenly distributed vacuum suction cups, which are firmly adsorbed on the surface by generating negative pressure through the vacuum pump system. Each suction cup is also connected to a spring buffer system, which can automatically adjust the adsorption force according to the surface fluctuations to avoid adsorption failure due to surface changes. The vacuum control module dynamically adjusts the operation of the vacuum pump and the solenoid valve to ensure that the suction cup always maintains sufficient adsorption force on complex surfaces.

[0039] The hydraulic unit provides the robot with precise height and angle adjustment capabilities. The upper and lower frames are linked by hydraulic rods, and the hydraulic system controls the telescopic action of the rods to achieve dynamic adjustment, thereby adapting to surfaces of different curvatures and slopes. The multi-point support design further disperses stress and maintains structural stability. At the same time, the flexible height adjustment of the hydraulic unit allows the robot to fit the target surface as a whole, improving stability and efficiency during the climbing process.

[0040] The sensor module provides a basis for dynamic adjustment of the robot by monitoring the robot's position, posture and adsorption unit status in real time. The position and posture sensor detects the robot's tilt angle, the adsorption status sensor monitors the negative pressure of the suction cup, and the obstacle detection sensor sends a signal when it finds a protrusion or depression, triggering the robot to automatically adjust its action. This series of feedback mechanisms ensures that the robot remains safe and stable on complex terrain.

[0041] The robot also adopts a dynamic adjustment method of alternating multi-point adsorption and release. Different adsorption points are alternately adsorbed and released in sequence, and some suction cups are always fixed on the surface to maintain overall stability. The dynamic adjustment method of alternating multi-point adsorption and release realizes efficient collaborative operation by dividing the adsorption unit into a main adsorption unit and an auxiliary adsorption unit. The main adsorption unit is responsible for providing the main adsorption force to ensure stable contact between the robot and the surface; the auxiliary adsorption unit provides support when the main adsorption unit is released to prevent sliding or detachment. Each adsorption unit works together through real-time monitoring and intelligent control, dynamically assigns adsorption tasks according to the surface state, and optimizes the adsorption path. On irregular or inclined surfaces, the main adsorption unit is positioned in a relatively flat area, and the auxiliary adsorption unit uses a spring buffer system to adaptively adjust the pressure to fit the complex surface. This method improves the robot's adaptability to complex environments and adsorption stability, ensuring safe and efficient operation. Through the flexible adjustment of the hydraulic rod, the upper and lower frames can be adaptively adjusted according to surface changes to fit irregular surfaces to the greatest extent. In addition, the closed-loop control system combines sensor data to optimize adsorption points, hydraulic adjustment, and track paths to improve climbing accuracy.

[0042] In terms of materials and structure, the robot uses lightweight and high-strength materials to make the frame, which not only reduces the overall weight but also improves the ability to resist deformation, reducing the risk of gravity affecting the adsorption effect. The mechanical properties of the elliptical structure are evenly distributed, which can effectively maintain the balance of multi-point adsorption and complex surface environments, thereby further enhancing stability.

[0043] The elliptical ring-shaped adsorption and climbing composite robot is equipped with a power module, which provides necessary power support for the adsorption unit, hydraulic system, track system and multi-functional robot, ensuring that the composite robot can operate stably for a long time.

[0044] The following embodiments are described by taking a cleaning robot among multifunctional robots as an example.

[0045] Embodiment 1:

[0046] An adsorption unit of an elliptical ring adsorption climbing composite robot, such as Figure 1 As shown, the adsorption unit is installed between the upper and lower frames of the device, and mainly includes multiple vacuum suction cups, a spring buffer system and a vacuum control module, which are used to ensure the stable adsorption of the device on different curved surfaces.

[0047] Vacuum suction cups: The suction unit uses 16 vacuum suction cups, which are distributed between the upper and lower frames of the device. Each vacuum suction cup is made of wear-resistant material and can be firmly attached to the curved surface of various materials. The distribution position and number of suction cups are optimized according to the shape and size of the high-altitude irregular curved surface to ensure uniform and stable suction force on various curved surfaces.

[0048] Spring buffer system: In order to make the vacuum cups achieve efficient adsorption on different surfaces, the adsorption unit is equipped with a spring buffer system. Figure 3 Each vacuum suction cup is connected to a spring buffer device. When the device is adsorbed on a curved surface, the spring buffer system can automatically adjust the pressure of the suction cup to adapt to slight changes in the curved surface, thereby improving the adaptability of the adsorption unit and ensuring a stable and reliable adsorption effect.

[0049] Vacuum control module: The vacuum control module is used to control the adsorption state of each vacuum cup, including a vacuum pump and a solenoid valve system. The vacuum pump generates negative pressure to draw air out of the cup to form a strong adsorption force; the solenoid valve system is used to control the opening and closing state of each cup so that the adsorption can be quickly released when needed. The vacuum control module monitors and adjusts through an external control system to ensure that the device has a continuous adsorption force on complex surfaces.

[0050] Working process: Before the device starts to adsorb, the vacuum control module will adjust the number and position of the suction cups according to the conditions of the target surface. After starting the vacuum pump, the vacuum control module adsorbs each suction cup on the surface of the high-altitude irregular curved three-dimensional surface. During the adsorption process, the spring buffer system adjusts the pressure of the suction cup according to the surface fluctuations to ensure that the adsorption unit fits tightly with the surface. When it is necessary to detach from the surface, the solenoid valve opens quickly, the negative pressure in the suction cup is released, and the adsorption unit can be easily removed.

[0051] Through the above design, the adsorption unit can effectively adapt to a variety of curved surface environments, ensuring that the elliptical ring adsorption climbing device can obtain a safe and stable adsorption effect on different surfaces. This adsorption unit has a simple structure and reliable functions, providing key adsorption support for the elliptical ring adsorption climbing device, ensuring the safety and stability of high-altitude operations.

The cleaning module operates automatically as the robot moves along the track to ensure that the target surface is thoroughly cleaned.

[0056] Monitoring sensors: To ensure the accuracy and safety of the cleaning process, the cleaning robot is equipped with a variety of monitoring sensors, including distance sensors, posture sensors and obstacle detection sensors. The distance sensor can monitor the distance between the robot and the cleaning surface in real time to ensure consistent cleaning results; the posture sensor is used to detect the robot's tilt angle to adjust the cleaning posture; the obstacle detection sensor can trigger an alarm or automatically shut down the cleaning robot when it approaches an obstacle to ensure the safety of the cleaning process.

[0057] Control and communication module: The cleaning robot is connected to the external control system through the wireless communication module to achieve remote monitoring and data exchange. The external control system can monitor the operating status, position and sensor feedback information of the cleaning robot in real time, and adjust the robot's operating parameters according to task requirements. The control module can also automatically record the cleaning process data and upload it to the central monitoring system for operators to view and analyze.

[0058] Working process: After starting, the cleaning robot moves along the track through the drive system, activating the rotating brush and water spray device in the cleaning module to clean the surface in turn, and collecting impurities through the dust collector. The robot can adjust the travel speed and cleaning strength according to the information feedback from the monitoring sensor to ensure the precise completion of the cleaning task. If it encounters obstacles or uneven surfaces, the control system automatically adjusts the robot's posture or suspends operation to avoid damage.

[0059] Through the above design, the cleaning robot 2 can move flexibly along the circular track 3, adapt to the cleaning needs of various complex curved surfaces, and achieve efficient and uniform cleaning effects.

The sensor module monitors the system status in real time, and the control module dynamically adjusts the adsorption pressure and cleaning parameters according to the feedback to ensure the cleaning effect and safe operation. After the task is completed, the system releases the adsorption force, resets and turns off the power.
