Outdoor robots generally have their own specific operating routes and perform tasks according to their specific operating routes via a motion mechanism such as a drive wheel.

[0003] However, an outdoor robot deployed on an offshore platform is typically exposed to many harsh offshore environments, such as strong winds, heavy rainfall, and the like. This means the outdoor robot must pay attention to its running speed, balance, and other performance to overcome adverse environmental factors such as strong winds, heavy rainfall, and slippery ground.

[0004] The existing outdoor robot lacks an appropriate anti-tip structure and is prone to tipping over due to factors such as strong winds, heavy rainfall, and slippery ground. This can easily disrupt the normal operation of the offshore platform and, in serious cases, even damage the outdoor robot and cause economic losses. CONTENTS OF THE PRESENT UTILITY MODEL

[0019] In order to make the above-mentioned purposes, features and advantages of the present utility model clearer and easier to understand, the present utility model is described in more detail below together with the attached drawings and specific implementation methods.

[0020] The embodiments of the present utility model relate to an outdoor robot. The outdoor robot described in the embodiments of the present utility model is suitable for some work spaces with harsh environments where the outdoor robot is prone to tipping over, such as offshore operating platforms, deserts, and other natural environments with harsh natural conditions. For example, the offshore operating platform is exposed to strong winds and other influences throughout the year, and the ground is slippery. The outdoor robot exhibits poor stability during operation and is prone to tipping over due to strong winds.

[0021] To overcome the above environmental influences, with reference to Fig. 1, the outdoor robot of the present utility model is equipped with structures such as a wind direction sensor 2, a steering device 4, an auxiliary wheel 8, and a controller 3 on the robot body 1. The robot body 1 generally adopts an existing robot structure and can be the structure of a transport robot or the structure of an inspection robot depending on the application scenario. Regardless of the robot structure adopted by the robot body 1, the robot body 1 is equipped with a power source and a drive element. The drive element can be a crawler or a wheel. In use, the robot body 1 can move along a preset route using a power source and a drive element. The power source is generally an electric motor whose power output is connected to the drive element directly or via a transmission component, such as a gear.

[0022] However, the drive element alone cannot withstand the effects of strong winds and other influences on outdoor robots. For this purpose, structures such as a wind direction sensor 2, a steering device 4, a controller 3, and an auxiliary wheel 8 are provided on the robot body 1. With reference to Fig. 1, the wind direction sensor 2 is arranged on the robot body 1, and several wind direction sensors are arranged around the robot body 1 to detect the wind direction in the environment in which the outdoor robot is located. The wind direction sensor 2 can only be activated when the wind strength reaches a certain level, generally when the wind strength reaches the strong wind level. Strong wind level generally refers to winds that reach Beaufort scale 8 near the ground, i.e., an average wind speed of 17.2 to 20.7 m / s or more. In some cases, winds on the Beaufort scale 6, with an average wind speed of 10.8 to 13.8 m / s or more, can also be considered strong winds. When the outdoor robot is located in a strong wind environment, one or more wind direction sensors 2 facing the wind direction receive a certain wind strength and send a wind direction signal to the controller 3.

[0023] After receiving the wind direction signal, the controller 3 controls the steering device 4 to change the direction of the auxiliary wheel 8 according to the signal from the corresponding wind direction sensor 2, causing the robot to change its direction of movement during operation and move in the direction of the wind. This prevents strong winds from blowing over the outdoor robot from the side in the running direction of the outdoor robot, thereby affecting the normal movement and operation of the outdoor robot. The direction facing the wind direction includes the direction facing the wind direction and the direction slightly inclined from the direction facing the wind direction. That is, the direction facing the wind direction in the embodiments of the present utility model refers to a fan-shaped directional range facing the wind direction, wherein the directional range is determined by the activated wind direction sensor 2.

[0024] The controller 3 adopts an existing control structure. A communication line is provided between the controller and the wind direction sensor 2, and a wind direction signal sent from the wind direction sensor 2 after triggering is received via the communication line. After receiving the trigger signal, the controller 3 can control the steering device 4 to steer, thereby turning the auxiliary wheel 8 in the wind direction. This allows the robot to change its moving direction and move in the wind direction during operation, which is intended to prevent the strong wind from blowing over the outdoor robot from the side in the running direction of the outdoor robot and thereby affecting the normal movement and operation of the outdoor robot. In the present embodiment, the controller 3 is specifically arranged inside the robot body 1 to prevent malfunctions of the controller 3 due to environmental influences.

[0025] The rotation of the steering device 4 depends on the predefined travel route. That is, when the outdoor robot is operating normally, the robot body 1 moves along a predefined route on the offshore operating platform under its own or external control. The steering device 4 drives the auxiliary wheel 8 to steer according to a predefined route, thus adjusting the forward direction of the outdoor robot. When the robot body 1 is in a strong wind environment, one or more wind direction sensors 2 on the robot body 1 receive a specific wind force based on environmental factors such as wind strength and send a wind direction signal to the controller 3.After receiving the wind direction signal, the controller 3 controls the steering device 4 to change the direction of the auxiliary wheel 8 according to the signal from the corresponding wind direction sensor 2, whereby the robot changes its direction of movement and moves in the direction of the wind during operation.

[0026] Based on the above structure, the robot body 1 may include a cylindrical shell 11 and an arcuate dome 12, and the cylindrical shell 11 and the arcuate dome 12 are firmly connected to each other to form a relatively enclosed interior of the robot body 1. Accordingly, both the controller 3 and the steering device 4 are arranged inside the cylindrical shell 11, and the wind direction sensor 2 is arranged outside the cylindrical shell 11 to receive information about strong winds. The auxiliary wheel 8 is arranged under the cylindrical shell to drive the outdoor robot when moving for steering and also to help it maintain stability.

[0027] Specifically, four to eight wind direction sensors 2 can be provided and evenly arranged along the circumferential direction of the cylindrical shell 11. This allows the outdoor robot to detect the wind direction as comprehensively as possible. For example, if four wind direction sensors 2 are evenly arranged in the circumferential direction of the cylindrical shell 11, the four wind direction sensors 2 can be arranged on the same horizontal circumference, and any two adjacent wind direction sensors 2 are spaced 90 degrees apart. The four wind direction sensors 2 each correspond to the four cardinal directions of east, south, west, and north.For convenience, the wind direction sensor 2 corresponding to the east direction is referred to as wind direction sensor 2A, the wind direction sensor 2 corresponding to the south direction is referred to as wind direction sensor 2B, the wind direction sensor 2 corresponding to the west direction is referred to as wind direction sensor 2C, and the wind direction sensor 2 corresponding to the north direction is referred to as wind direction sensor 2D. When the outdoor robot is hit by strong east winds, the wind direction sensor 2A is activated and sends a wind direction signal A to the controller 3. After receiving the wind direction signal A, the controller 3 controls the steering device 4 to drive the auxiliary wheel 8 to rotate east. When the outdoor robot is hit by strong south winds, the wind direction sensor 2B is activated and sends a wind direction signal B to the controller 3.After receiving the wind direction signal B, the controller 3 controls the steering device 4 to drive the auxiliary wheel 8 to rotate south. When the outdoor robot is hit by strong westerly winds, the wind direction sensor 2C is activated and sends a wind direction signal C to the controller 3. After receiving the wind direction signal C, the controller 3 controls the steering device 4 to drive the auxiliary wheel 8 to rotate west. When the outdoor robot is hit by strong northerly winds, the wind direction sensor 2D is activated and sends a wind direction signal D to the controller 3. After receiving the wind direction signal D, the controller 3 controls the steering device 4 to drive the auxiliary wheel 8 to rotate north.

[0028] When the outdoor robot is hit by strong southeast winds, both the wind direction sensor 2A and the wind direction sensor 2B are activated and send the wind direction signal A and the wind direction signal B to the controller 3. After the controller 3 simultaneously receives the wind direction signal A and the wind direction signal B, the controller controls the steering device 4 to drive the auxiliary wheel 8 to rotate southeast. When the outdoor robot is hit by strong southwest winds, the wind direction sensor 2B and the wind direction sensor 2C are activated and send the wind direction signal B and the wind direction signal C to the controller 3, respectively. After receiving the wind direction signal B and the wind direction signal C, the controller 3 controls the steering device 4 to drive the auxiliary wheel 8 to rotate southwest.When the outdoor robot is hit by strong northeast winds, the wind direction sensor 2A and the wind direction sensor 2D are activated and send the wind direction signal A and the wind direction signal D to the controller 3, respectively. After the controller 3 receives the wind direction signal A and the wind direction signal D, the controller controls the steering device 4 to drive the auxiliary wheel 8 to rotate northeast. When the outdoor robot is hit by strong northwest winds, the wind direction sensor 2C and the wind direction sensor 2D are activated and send the wind direction signal C and the wind direction signal D to the controller 3. After the controller 3 receives the wind direction signal C and the wind direction signal D, the controller controls the steering device 4 to drive the auxiliary wheel 8 to rotate northwest.The wind direction signal A, the wind direction signal B, the wind direction signal C and the wind direction signal D are all level signals output by the wind direction sensor 2.

[0029] For example, if eight wind direction sensors 2 are evenly arranged in the circumferential direction of the cylindrical shell 11, the eight wind direction sensors 2 may be arranged on the same horizontal circumference, and any two adjacent wind direction sensors 2 are spaced 45 degrees apart. The eight wind direction sensors 2 correspond to the eight cardinal directions of east, south, west, north, southeast, northeast, southwest, and northwest, respectively. For convenience of naming, the wind direction sensor 2 corresponding to the east direction is referred to as wind direction sensor 2a, the wind direction sensor 2 corresponding to the south direction is referred to as wind direction sensor 2b, the wind direction sensor 2 corresponding to the west direction is referred to as wind direction sensor 2c, and the wind direction sensor 2 corresponding to the north direction is referred to as wind direction sensor 2d.The wind direction sensor 2 corresponding to the southeast direction is the wind direction sensor 2e, the wind direction sensor 2 corresponding to the southwest direction is the wind direction sensor 2f, the wind direction sensor 2 corresponding to the northeast direction is the wind direction sensor 2g, and the wind direction sensor 2 corresponding to the northwest direction is the wind direction sensor 2h. When the outdoor robot is hit by a strong east wind, the wind direction sensor 2a is activated and sends a wind direction signal a to the controller 3. After receiving the wind direction signal a, the controller 3 controls the steering device 4 to drive the auxiliary wheel 8 to rotate east. When the outdoor robot is hit by a strong south wind, the wind direction sensor 2b is activated and sends a wind direction signal b to the controller 3.After receiving the wind direction signal b, the controller 3 controls the steering device 4 to drive the auxiliary wheel 8 to rotate south. When the outdoor robot is hit by strong westerly winds, the wind direction sensor 2c is activated and sends a wind direction signal c to the controller 3. After receiving the wind direction signal c, the controller 3 controls the steering device 4 to drive the auxiliary wheel 8 to rotate west. When the outdoor robot is hit by strong northerly winds, the wind direction sensor 2d is activated and sends a wind direction signal d to the controller 3. After receiving the wind direction signal d, the controller 3 controls the steering device 4 to drive the auxiliary wheel 8 to rotate north. When the outdoor robot is hit by strong southeastern winds, the wind direction sensor 2e is activated and sends a wind direction signal e to the controller 3.After receiving the wind direction signal e, the controller 3 controls the steering device 4 to drive the auxiliary wheel 8 to rotate southeast. When the outdoor robot is hit by strong southwest winds, the wind direction sensor 2f is activated and sends a wind direction signal f to the controller 3. After receiving the wind direction signal f, the controller 3 controls the steering device 4 to drive the auxiliary wheel 8 to rotate southwest. When the outdoor robot is hit by strong northeast winds, the wind direction sensor 2g is activated and sends a wind direction signal g to the controller 3. After receiving the wind direction signal g, the controller 3 controls the steering device 4 to drive the auxiliary wheel 8 to rotate northeast. When the outdoor robot is hit by strong northwest winds, the wind direction sensor 2h is activated and sends a wind direction signal h to the controller 3.Upon receiving the wind direction signal h, the controller 3 controls the steering device 4 to drive the auxiliary wheel 8 to rotate northwest. Similarly, the wind direction signal a, the wind direction signal b, the wind direction signal c, the wind direction signal d, the wind direction signal e, the wind direction signal f, the wind direction signal g, and the wind direction signal h are all level signals output from the wind direction sensor 2.

[0030] The arrangement of five, six or seven wind direction sensors 2 can already be mentioned above and will not be described in detail here.

[0031] Based on the above structure, further reference to Fig. 1, the outdoor robot may also include a drive wheel 7 and a reduction gear 6. The drive wheel 7 is rotatably mounted at the lower end of the cylindrical shell 11 to move the robot body 1. The reduction gear 6 is also arranged on the robot body 1. After the controller 3 receives the wind direction signal from the wind direction sensor 2, the controller 3 can control the reduction gear 6 to reduce the traveling speed of the robot body 1 to help the robot body 1 remain as stable as possible.

[0032] With reference to Fig.2, the reduction gear 6 specifically includes a reduction telescopic rod 61 and a friction damping structure 62 disposed at the extended end of the reduction telescopic rod 61. The friction damping structure 62 may be a rubber pad, a patterned steel plate with an anti-slip pattern, or the like, which has high frictional damping with the ground. The fixed end of the reduction telescopic rod 61 is fixed to the outer lower end of the cylindrical shell 11, and the extended end is disposed toward the ground; the friction damping structure 62 is provided at the extended end of the reduction telescopic rod 61 to abut the ground and reduce the traveling speed of the robot body 1. The reduction telescopic rod 61 may be an existing telescopic rod structure, such as a hydraulic telescopic rod, a pneumatic telescopic rod, or the like.When the wind direction sensor 2 on the outdoor robot sends a wind direction signal, the reduction telescopic rod 61 is extended under the control of the controller 3, bringing the friction damping structure 62 into contact with the ground, thereby increasing the frictional resistance between the outdoor robot and the ground and thus reducing the traveling speed of the outdoor robot. Furthermore, the reduction telescopic rod 61 and the friction damping structure 62 can also provide support for the robot body 1 to help keep the robot body 1 stable when the robot body 1 slides sideways.

[0033] Of course, the reduction gear 6 can also have other designs. For example, the reduction gear 6 can also be a rim brake structure arranged on the drive wheel 7. When the wind direction sensor 2 on the outdoor robot sends the wind direction signal, the brake caliper of the rim brake structure, under the control of the controller 3, clamps the drive wheel 7 of the outdoor robot to reduce the driving speed of the outdoor robot. Alternatively, the reduction telescopic rod 61 can be replaced by a scissor-like telescopic structure, in which case the friction damping structure 62 is arranged at the extended end of the scissor-like telescopic structure. Alternatively, the reduction telescopic rod 61 can be replaced by a rigid rocker arm hinged to the robot body 1, and the friction damping structure 62 is arranged at the end of the rigid rocker arm.When the wind direction sensor 2 on the outdoor robot sends a wind direction signal, the rigid rocker arm folds down under the control of the controller 3, so that the friction damping structure 62 rests on the ground to reduce the driving speed of the outdoor robot. The rigid rocker arm can be driven by an electric motor, a hydraulic cylinder, or an air cylinder.

[0034] Preferably, at least two reduction gears 6 may be provided. Compared with the technical solution in which only one reduction gear 6 is mounted on the robot body 1, if the structure and size of the reduction gear 6 are not changed, at least two reduction gears 6 are provided, thereby achieving stronger friction damping when the outdoor robot slips sideways and achieving more effective deceleration. During implementation, two or three reduction gears 6 can basically be provided on the robot body 1, taking into account the installation space. Of course, in some special cases, such as a relatively large outdoor robot, the number of reduction gears 6 may be larger, specifically four, five, or even more. Of course, only one reduction gear 6 may be provided on the robot body 1 to reduce the machining cost of the outdoor robot.The arrangement of the at least two reduction gears 6 on the robot body 1 can be specifically determined according to actual requirements. For example, if three reduction gears 6 are provided on the robot body 1, the reduction gears 6 can be arranged evenly along the circumferential direction of the robot body 1, that is, the reduction gears 6 are arranged in a ". "-shape on the robot body 1. The reduction gears 6 can also be arranged side by side on the robot body 1 along a specific direction or in a row on the robot body 1. The exact number and position of the reduction gears 6 arranged on the robot body 1 depend on the actual requirements and are not described in detail here.

[0035] In the design, the reduction gear 6 is preferably arranged at the lower end of the robot body 1. In this way, the extension stroke of the reduction gear 6 can be shortened, which allows the reduction gear 6 to be moved into the correct position in a timely manner when the outdoor robot is exposed to strong winds. This can improve the reliability of the reduction gear 6 and prevent the outdoor robot from being severely damaged by strong winds before the reduction gear 6 is moved into place. Furthermore, this also contributes to the miniaturization of the reduction gear 6, thus helping to reduce the production and processing costs of the outdoor robot.

[0036] In the outdoor robot of the embodiments of the present utility model, the steering device 4 specifically includes a steering wheel 41 and a drive component, wherein the steering wheel 41 is rotatably mounted on the inner lower end of the cylindrical shell 11, and the auxiliary wheel 8 is mounted on the steering wheel 41. The arrangement of the steering wheel 41 facilitates the mounting of the auxiliary wheel 8 and also provides a good transmission path for the drive component to drive the auxiliary wheel 8 for steering. Specifically, the drive component may be a bidirectional drive motor. A bidirectional drive motor is a drive motor that can rotate both forward and reverse. Under the control of the controller 3, the bidirectional drive motor can drive the steering wheel 41 to rotate it to a predetermined position. The power output of the bidirectional drive motor is drivingly connected to the steering wheel 41 via a transmission rod, i.e., a transmission rod.That is, the output terminal of the bidirectional drive motor is coaxially connected to the transmission rod, and the transmission rod is coaxially connected to the steering wheel 41. In this way, the torque output from the bidirectional drive motor can directly act on the steering wheel 41, effectively simplifying the transmission path, simplifying the structure of the steering device 4, and reducing the implementation cost of the steering device 4.

[0037] Of course, the steering wheel 41 can also be a toothed disk, i.e., the outer peripheral surface of the steering wheel 41 has meshing teeth. The auxiliary wheel 8 is mounted on the ground-facing side of the toothed disk. The bidirectional drive motor is mounted on the robot body 1, and the power output of the bidirectional drive motor is meshed with the toothed disk via a set of gear sets or rod sets.

[0038] The outdoor robot may further include a wind sensor 5 and a reclaimer. The wind sensor 5 is arranged on the arched dome 12 to detect the wind strength in the environment where the robot body 1 is located. When the wind strength in the environment where the robot body 1 is located exceeds the strong wind strength and reaches the storm strength, the wind sensor 5 is activated and sends a wind strength signal to the reclaimer. The reclaimer is pre-equipped with a home navigation system. When the reclaimer receives the wind strength signal, it can force the robot body 1 to stop all actions and control the drive wheel 7 and the auxiliary wheel 8 to return to a safe position along a preset route. This means that the action priority of the reclaimer is higher than that of the other devices.This can prevent the outdoor robot from being operated in an environment with strong winds and prevent the outdoor robot from being damaged by strong winds.

[0039] In summary, when the outdoor robot of the embodiments of the present utility model is moving normally on the offshore operating platform, in strong winds, the wind direction sensor 2 on the outdoor robot is activated, and the wind direction signal is sent to the controller 3. After receiving the wind direction signal, the controller 3 controls the auxiliary wheel 8 to rotate in the wind direction to ensure that the outdoor robot is not affected by wind forces from directions other than the traveling direction. At the same time, the auxiliary wheel 8 also provides good support for the robot body 1. On the other hand, under the control of the controller 3, the reduction telescopic rod 61 is extended, so that the friction damping structure 62 is brought into contact with the ground, thereby increasing the frictional resistance between the outdoor robot and the ground and thus reducing the traveling speed of the outdoor robot.

[0040] When the wind strength in the environment where the outdoor robot is located decreases, the reduction gear 6 is retracted so that the outdoor robot can continue its normal operation.

[0041] The above only represents specific embodiments of the present utility model, but the scope of the present utility model is not limited thereto. Anyone familiar with the technical field can easily imagine modifications or substitutions within the technical scope disclosed in the present utility model, and these should be covered by the scope of the present utility model. Therefore, the scope of the present utility model should be subject to the scope of the claims.

[0042] It should be noted that for the average person skilled in the art, some improvements and modifications are also made, which are to be considered as part of the scope of protection of the present utility model, without deviating from the principle of the present utility model.

[0043] Finally, it should be noted that in this article, relational terms such as "first" and "second" or the like are used merely to distinguish one entity or operation from another entity or operation and do not necessarily require or imply any actual relationship or sequence between those entities or operations. Furthermore, the terms "comprise," "include," or other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, item, or terminal comprising a set of elements includes not only those elements but also other elements not explicitly listed or even elements inherent in that process, method, item, or terminal.
