Description
Technical Field
[0001] This utility model belongs to the field of underwater robot technology, and more specifically, it relates to an underwater flaw detection robot. Background Technology
[0002] An underwater flaw detection robot is an intelligent device specifically designed for non-destructive testing in underwater environments. It can work stably in complex and ever-changing underwater environments and perform various tasks, such as underwater exploration, monitoring, search and rescue, salvage, and construction.
[0003] When conducting flaw detection on the surface of an underwater ship or the wall of a hydroelectric dam, an underwater flaw detection robot needs to fit close to the surface of the ship or the wall of the hydroelectric dam and move around to facilitate the detection of damage to the surface and wall. However, there are usually a lot of aquatic plants and debris in the water, and when the underwater flaw detection robot moves, its detection head is prone to getting entangled with aquatic plants or debris, thus reducing its safety. Utility Model Content
[0004] To address the problem that the detection head of an underwater flaw detection robot easily gets entangled with aquatic plants or debris during movement, thus affecting its detection effect, this utility model proposes an underwater flaw detection robot to overcome the aforementioned technical problems existing in the prior art.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model relates to an underwater flaw detection robot, comprising a robot body:
[0007] The robot body is equipped with a drive assembly, a lifting assembly, a detection assembly, a snap-fit assembly, and a rotation assembly.
[0008] The drive component has its output end fixedly installed at one end of the lifting component, so that the drive component drives the lifting component to move up and down.
[0009] The detection component is rotatably mounted at its bottom end to the top end of the lifting component, so that the detection component is driven to move when the lifting component moves up and down.
[0010] The snap-fit component has one end snap-fitted into the interior of the lifting component, so that the snap-fit component snaps and fixes the lifting component, so that the lifting component can operate when the drive component is started.
[0011] The bottom end of the rotating component is fixedly connected to the top end of the lifting component, so that the rotating component moves along with the lifting component.
[0012] Furthermore, the drive assembly includes a mounting frame, the bottom end of which is fixedly mounted to the interior of the robot body, and a micro motor is fixedly mounted on the bottom end of the mounting frame.
[0013] Furthermore, the lifting assembly includes a threaded rod, one end of which is fixedly installed to the output end of a micro motor, and a threaded seat is threadedly connected to the threaded surface of the threaded rod, with a lifting plate rotatably mounted on the outer surface of the threaded seat.
[0014] Furthermore, the detection component includes a mounting plate, the bottom end of which is rotatably mounted to the top end of the lifting plate, and a detection probe is fixedly mounted on the top end of the mounting plate.
[0015] Furthermore, the snap-fit assembly includes a fixing frame and a top block. One side of the fixing frame is fixedly connected to one side of the lifting plate. A limit block is slidably arranged inside the fixing frame. A spring piece is arranged inside the limit block. The bottom end of the spring piece is fixedly installed to the inner side of the fixing frame.
[0016] Furthermore, the snap-fit assembly also includes a snap-fit groove, which is formed on the outer surface of the threaded seat. A snap-fit block is snap-fitted inside the snap-fit groove. A spring is fixedly connected inside the snap-fit block. A sliding rod is fixedly connected to one end of the spring. One end of the sliding rod is fixedly connected to one side of the limiting block.
[0017] Furthermore, the rotating assembly includes a first synchronous pulley, the bottom end of which is fixedly connected to the top end of the threaded seat, a synchronous belt is driven on the inner side of the first synchronous pulley, and a second synchronous pulley is driven on the inner side of the synchronous belt, the top end of which is fixedly connected to the bottom end of the mounting plate.
[0018] This utility model has the following beneficial effects:
[0019] 1. This utility model activates a drive component, causing a lifting component mounted on its output end to rise. This, in turn, moves a detection component mounted on its top upwards, extending it out of the robot body. This facilitates the inspection of the surface of a ship or dam. As the lifting component continues to move, it causes a locking component to move to a fixed position. This releases the locking component, allowing the lifting component to rotate without moving upwards or downwards. This, in turn, causes a rotating component fixed on its top to rotate, which in turn rotates the detection component. As a result, the detection component retracts into its interior before the robot body reaches the designated position, preventing weeds or debris from entangled on the surface of the detection component and thus improving its safety.
[0020] 2. When the threaded rod rotates, it drives the threaded seat to rotate, which in turn drives the first synchronous wheel fixed at its top to rotate. This drives the synchronous belt on the inner side to rotate, which in turn drives the second synchronous wheel on the inner side to rotate. This drives the mounting plate fixed at its top to rotate, so as to adjust the direction of the detection probe mounted at its top, thus enabling it to be used for detection at different angles.
[0021] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0031] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.
[0032] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.
[0033] Please see Figures 1-6 As shown, this utility model is an underwater flaw detection robot, including a robot body 1:
[0034] The robot body 1 is equipped with a drive assembly 2, a lifting assembly 3, a detection assembly 4, a snap-fit assembly 5, and a rotation assembly 6.
[0035] The output end of the drive component 2 is fixedly installed to one end of the lifting component 3, so that the drive component 2 drives the lifting component 3 to move up and down.
[0036] The detection component 4 is rotatably mounted at its bottom end to the top end of the lifting component 3, so that the detection component 4 is driven to move when the lifting component 3 moves up and down.
[0037] The snap-fit component 5 has one end snap-fitted into the interior of the lifting component 3 so that the snap-fit component 5 snaps and fixes the lifting component 3 so that the lifting component 3 can operate when the driving component 2 is started.
[0038] The bottom end of the rotating component 6 is fixedly connected to the top end of the lifting component 3 so that the rotating component 6 moves along with the lifting component 3.
[0039] In use, by activating the drive component 2, the lifting component 3 installed at its drive output end is raised, thereby driving the detection component 4, which is rotated and installed at its top, to move upward and extend into the robot body 1, thus facilitating the inspection of the ship hull or dam surface. As the lifting component 3 continues to move, it drives the locking component 5 to move to a fixed position, which releases the locking component 5 from the lifting component 3, allowing the lifting component 3 to rotate without moving up or down. This drives the rotating component 6, which is fixed at its top, to rotate. Since the top of the rotating component 6 is fixedly connected to the bottom of the detection component 4, when the rotating component 6 rotates, it drives the detection component 4 to rotate, thus facilitating all-round inspection of the ship hull or dam surface.
[0040] This invention activates the drive assembly 2, causing the lifting assembly 3 installed at its drive output end to rise. This, in turn, moves the detection assembly 4, which is rotated and installed at its top, upward and extends it out of the robot body 1. This facilitates the inspection of the surface of a ship or dam. As the lifting assembly 3 continues to move, it causes the locking assembly 5 to move to a fixed position. This releases the locking assembly 5, allowing the lifting assembly 3 to rotate without moving upward or downward. This causes the rotating assembly 6, which is fixed at its top, to rotate, thereby rotating the detection assembly 4. When the robot body has not reached the designated position, the detection assembly 4 retracts into its interior, preventing the surface of the detection assembly 4 from becoming entangled with weeds or debris, thus improving the safety of the detection assembly 4.
[0041] In one embodiment, the drive component 2 includes a mounting frame 201, the bottom end of which is fixedly mounted to the inside of the robot body 1, and a micro motor 202 is fixedly mounted on the bottom end of the mounting frame 201.
[0042] The mounting bracket 201 is installed on the robot body 1, thereby supporting and limiting the micro motor 202 installed at its bottom, which improves the stability of the micro motor 202. In addition, the micro motor 202 is a waterproof motor, which improves the stability of the underwater flaw detection robot during underwater operation.
[0043] In one embodiment, the lifting assembly 3 includes a threaded rod 301, one end of which is fixedly installed with the output end of the micro motor 202. The threaded surface of the threaded rod 301 is threadedly connected to a threaded seat 302, and a lifting plate 303 is rotatably disposed on the outer surface of the threaded seat 302.
[0044] The micro motor 202 drives the threaded rod 301 installed at the output end to rotate. Since the threaded surface of the threaded rod 301 is connected to the internal thread of the threaded seat 302, and the threaded seat 302 is engaged with the snap-fit component 5, the rotation of the threaded rod 301 can be restricted. Thus, when the threaded rod 301 rotates, it can drive the threaded seat 302 connected to its threaded surface to move, so that it can drive the lifting plate 303 with its outer surface rotating to move up and down.
[0045] In one embodiment, the detection component 4 includes a mounting plate 401, the bottom end of which is rotatably mounted to the top end of the lifting plate 303, and a detection probe 402 is fixedly mounted on the top end of the mounting plate 401.
[0046] When the lifting plate 303 moves up and down with the threaded seat 302, it can drive the mounting plate 401, which is rotatably mounted on its top, to move, so that the detection probe 402 mounted on its top can move, making it easier to put into or out of the robot body 1, thereby improving the safety of the detection probe 402.
[0047] In one embodiment, the snap-fit assembly 5 includes a fixing frame 501 and a top block 502. One side of the fixing frame 501 is fixedly connected to one side of the lifting plate 303. A limit block 503 is slidably arranged inside the fixing frame 501. A spring piece 504 is arranged inside the limit block 503. The bottom end of the spring piece 504 is fixedly installed to the inner side of the fixing frame 501.
[0048] The snap-fit assembly 5 also includes a snap-fit groove 505, which is formed on the outer surface of the threaded seat 302. A snap-fit block 506 is snap-fitted inside the snap-fit groove 505. A spring 507 is fixedly connected inside the snap-fit block 506. A sliding rod 508 is fixedly connected to one end of the spring 507. One end of the sliding rod 508 is fixedly connected to one side of the limiting block 503.
[0049] When the lifting plate 303 moves, it can drive the fixed frame 501 fixedly connected to one side to move, so that it can drive the internally sliding limit block 503 to move, and during the continuous movement, the top end of the limit block 502 will be in contact with the bottom end of the top block 502, and compress the internally set spring piece 504. At the same time, it can drive the sliding rod 508 fixed on one side to move downward relative to the fixed frame 501, thereby driving the spring 507 fixed at one end to move, and driving the locking block 506 fixed at one end to move. Thus, when it moves inside the locking groove 505, it can release the locking setting between itself and the locking groove 505, so that the threaded seat 302 can rotate with the rotation of the threaded rod 301, thereby preventing the lifting plate 303 from moving upward continuously. When the threaded seat 302 rotates in the opposite direction, it can engage with the locking groove 505 and the locking block 506 again, thereby facilitating its downward movement.
[0050] In one embodiment, the rotating assembly 6 includes a first synchronous pulley 601, the bottom end of which is fixedly connected to the top end of the threaded seat 302. A synchronous belt 602 is driven on the inner side of the first synchronous pulley 601, and a second synchronous pulley 603 is driven on the inner side of the synchronous belt 602. The top end of the second synchronous pulley 603 is fixedly connected to the bottom end of the mounting plate 401.
[0051] When the threaded seat 302 rotates along with the threaded rod 301, it drives the first synchronous pulley 601 fixed at its top to rotate, which in turn drives the synchronous belt 602 on the inner transmission side to rotate, thereby driving the second synchronous pulley 603 on the inner transmission side to rotate, which in turn drives the mounting plate 401 fixed at its top to rotate, so as to adjust the direction of the detection probe 402 mounted at its top, thus enabling it to be used for detection at different angles.
[0052] Through the above technical solution, 1. By activating the drive component 2, the lifting component 3 installed at its drive output end is raised, thereby driving the detection component 4 installed at its top to move upward and extend it out of the robot body 1, thus facilitating the detection of the ship hull or dam surface. As the lifting component 3 continues to move, it drives the locking component 5 to move to a fixed position, which can release the locking and fixing of the lifting component 3, thereby causing the lifting component 3 to rotate without moving up or down, thereby driving the rotating component 6 fixed at its top to rotate, which in turn drives the detection component 4 to rotate, so that the detection component 4 retracts into its interior before the robot body reaches the designated position, thereby preventing the surface of the detection component 4 from being entangled with weeds or debris, thus improving the safety of the detection component 4.
[0053] 2. When the threaded rod 301 rotates, it drives the threaded seat 302 to rotate, which in turn drives the first synchronous pulley 601 fixed at its top to rotate, which in turn drives the synchronous belt 602 on the inner transmission side to rotate, which in turn drives the second synchronous pulley 603 on the inner transmission side to rotate, which in turn drives the mounting plate 401 fixed at its top to rotate, so as to adjust the direction of the detection probe 402 mounted at its top, thus enabling it to be used for detection at different angles.
