It is usually designed for use in industrial, commercial and even military fields to perform tasks that are highly repetitive, in harsh environments or are too dangerous for humans.

DETAILED DESCRIPTION

[0042] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0043] See also Figure 1-Figure 16 , an explosion-proof structure and a wheeled inspection robot, comprising an explosion-proof battery compartment body 2, the interior of the explosion-proof battery compartment body 2 is divided into a plurality of identical storage ports 26, a side of the explosion-proof battery compartment body 2 away from the openings of the plurality of storage ports 26 is connected to a plurality of power mechanisms, the output ends of the plurality of power mechanisms penetrate the outer shell of the explosion-proof battery compartment body 2 to the interior of the explosion-proof battery compartment body 2, and the ends of the plurality of power mechanisms located inside the explosion-proof battery compartment body 2 are connected to a buffer component and a moving component, the ends of the plurality of buffer components away from the power mechanisms are respectively connected to the plurality of moving components, the interiors of the plurality of moving components are connected to a protective component, the exteriors of the plurality of protective components are connected to a smoke sensor 37 and a temperature sensor 31, the interiors of the plurality of protective components are connected to replaceable batteries 12, the plurality of replaceable batteries 12 match the openings of the plurality of storage ports 26, the ends of the plurality of moving components away from the buffer component are connected to two groups of symmetrically arranged rotating components, the other ends of the two groups of rotating components are simultaneously connected to a shielding component, and the shielding component matches and aligns with the openings of the storage ports 26.

[0044] The explosion-proof structure and wheeled inspection robot of the present invention are similar to the existing wheeled inspection robot structure, such as an explosion-proof inspection robot disclosed in the patent with announcement number CN221496075U. Figures 1 to 16 As shown, when the explosion-proof structure and wheeled inspection robot of the present invention need to replace the battery, the following steps can be followed:

[0045] 1. When all batteries in the explosion-proof battery compartment 2 are about to run out of power, and only enough power is left to return to the place where the batteries are replaced, the entire explosion-proof robot body 1 can be controlled by the internal controller of the explosion-proof robot body 1 to start returning;

[0046] 2. When the explosion-proof robot body 1 returns to the battery replacement location, the remaining replaceable battery 12 normally supplies power to the controller inside the explosion-proof robot body 1, and then the controller starts one of the power mechanisms other than the power supply;

[0047] 3. As the power mechanism is activated, its output end will slowly extend outward, and during the extension process, the pressure will not be greater than the pressure of the buffer component itself, thereby pushing the buffer component and the moving component toward the opening of the storage port 26;

[0048] 4. When the moving component is pushed, the two rotating components at the other end will be pushed to move together, and when the two rotating components move, they will drive the shielding component at the other end to rotate downward;

[0049] 5. When the shielding component rotates, the opening of the storage port 26 will be opened, and the replacement personnel can then pull out the replaceable battery 12 inside the protective component, and then insert a fully charged new replaceable battery 12;

[0050] 6. After the first new replaceable battery 12 is inserted into the original storage port 26, the above steps can be reversed to fix the replaceable battery 12, and then the replaceable battery 12 can be used to supply power to the explosion-proof robot body 1. Then, the other replaceable batteries 12 can be replaced according to the above steps.

[0051] 7. When all the replaceable batteries 12 are replaced, the explosion-proof robot body 1 can continue to perform the inspection task, which is convenient and fast;

[0052] 8. In addition, during use, the replaceable battery 12 may experience thermal runaway and other conditions, and the replaceable battery 12 may spontaneously combust. In order to prevent the spontaneously combusting replaceable battery 12 from causing damage to the explosion-proof robot body 1, the replaceable battery 12 inside the protective component may be monitored in real time through the smoke sensor 37 and the temperature sensor 31;

[0053] 9. When the monitoring detects that a fire is about to occur, the internal controller of the explosion-proof robot body 1 immediately switches the power supply (for example, the No. 1 battery is originally powered, and when the No. 1 battery has thermal runaway, the controller immediately switches to the No. 2 battery for power supply). At this time, the internal controller of the explosion-proof robot body 1 immediately starts the first power mechanism with the help of the second power supply;

[0054] 10. At this time, the power mechanism is not pushed out slowly, but quickly. At this time, the moving component will move instantly, and after moving to a certain distance (that is, the original elongation of the battery replacement), it cannot move further, but the power mechanism will overcome the buffer component and compress the buffer component;

[0055] 11. After the buffer component is compressed, the protective component originally located inside the mobile component and the replaceable battery 12 located inside the protective component will be pushed outward;

[0056] 12. When the power mechanism reaches the maximum extension, the protection component has extended from the inside of the explosion-proof battery compartment 2 to a distance outside the explosion-proof battery compartment 2, and because the power mechanism cannot continue to extend, the protection component will also stop abruptly;

[0057] 13. Afterwards, the replaceable battery 12 will continue to move outward for a distance due to the inertia of the previous rapid movement, until it falls from the inside of the protective component to the outside of the explosion-proof robot body 1, thereby preventing the replaceable battery 12 from causing damage to the explosion-proof robot body 1;

[0058] 14. When the replaceable battery 12 slides to the outside of the explosion-proof battery compartment 2, the internal controller of the explosion-proof robot body 1 immediately controls the explosion-proof robot body 1 to continue moving away from the replaceable battery 12, thereby further reducing the degree of damage to the explosion-proof robot body 1.

[0059] Special mention should be made here:

[0060] 1. The controller and processor inside the explosion-proof robot body 1 are both existing technologies, so no detailed description is given for them;

[0061] 2. When the capacity of the replaceable battery 12 is sufficient, only two replaceable batteries 12 can be installed inside an explosion-proof robot body 1, so that the replaceable battery 12 can be replaced more quickly.

[0062] As a preferred solution of the present invention, the power mechanism includes an electric push rod 6 and a transmission rod 8. The outer wall of the electric push rod 6 is fixedly connected to the outer wall of the explosion-proof battery compartment 2. The output end of the electric push rod 6 passes through the interior of the explosion-proof battery compartment 2 to the storage port 26, and is fixedly connected to one end of the transmission rod 8. The other end of the transmission rod 8 is connected to the buffer assembly and the moving assembly.

[0063] More specifically, by providing a power mechanism, power can be provided when the replaceable battery 12 is normally replaced or the replaceable battery 12 is forcibly ejected.

[0064] Specifically, when it is necessary to push the moving component to move, it is only necessary to start the electric push rod 6 through the internal controller of the explosion-proof robot body 1. After the electric push rod 6 is started, the output end extends outward and pushes the transmission rod 8 to move together during the extension process. When the transmission rod 8 moves, it can push the moving component and the buffer component to move.

[0065] As a preferred solution of the present invention, the buffer assembly includes a plate No. 1 7, an extrusion spring 9, a connecting column 21 and two robot contact terminals 23, one end of the connecting column 21 is fixedly connected to the inner wall of the storage port 26, a spring cavity 22 is opened through the interior of the connecting column 21, the plate No. 1 7 is sleeved and fixedly connected to the outer wall of the transmission rod 8, the outer wall of the plate No. 1 7 is slidably connected to the inner wall of the spring cavity 22, the side of the plate No. 1 7 away from the electric push rod 6 is fixedly connected to one end of the extrusion spring 9, the other end of the extrusion spring 9 is connected to the moving assembly, one end of the two robot contact terminals 23 are respectively fixedly connected to two diagonals of the connecting column 21, and the other ends of the two robot contact terminals 23 are respectively matched and aligned with the two terminals of the replaceable battery 12.

[0066] More specifically, by providing a buffer component, the instantaneous elastic force can be buffered when the electric push rod 6 starts to eject the replaceable battery 12, thereby preventing the electric push rod 6 from directly acting on the protective component, causing the shielding component to not be opened, thereby affecting the sliding inertia of the replaceable battery 12.

[0067] Specifically, when the electric push rod 6 is started normally, the transmission rod 8 slowly extends outward. At this time, the No. 1 plate 7 will move together with the transmission rod 8, and the No. 1 plate 7 at this time will not cause too much pressure on the extrusion spring 9. Therefore, the extrusion spring 9 will push the moving component at the other end to move together. After the moving component moves, the shielding component can be opened by rotating the component.

[0068] When the electric push rod 6 starts quickly, the first plate 7 is pushed instantly, and the first plate 7 is likely to compress the extrusion spring 9 a little due to the momentary inertia force. Then, as the electric push rod 6 continues to extend, the moving component will be pushed outward by the extrusion spring 9 according to the above steps. The extrusion spring 9 is provided here to buffer this distance, so that the protective component inside the moving component will not start to move before the moving component has time to open the shielding component.

[0069] As a preferred embodiment of the present invention, the moving component includes an outer shell 10, two outer slides 11, a second plate 24, a plurality of pull ropes 30 and two groups of rotating components. One side of the outer wall of the outer shell 10 is fixedly connected to the end of the extrusion spring 9 away from the first plate 7. The second plate 24 is sleeved and fixedly connected to the outer wall of the end of the transmission rod 8. The second plate 24 is located in the outer shell 10, and the side of the second plate 24 away from the transmission rod 8 is fixedly connected to one end of the plurality of pull ropes 30. The other ends of the plurality of pull ropes 30 are connected to the protective component. The two outer slides 11 are respectively fixedly connected to the outer walls on both sides of the outer shell 10. External slide grooves 25 are provided on both sides of the inner wall of the storage port 26. The outer walls of the two outer slides 11 are respectively slidably connected to the inner walls of the two outer slide grooves 25. The end of the outer shell 10 away from the extrusion spring 9 is connected to the two rotating components.

[0070] More specifically, by setting up a moving component, firstly, the protective component can be stored and limited, and secondly, a partition can be provided between the power mechanism, the buffer component and the protective component to prevent the force of the power mechanism and the buffer component from directly acting on the protective component.

[0071] Specifically, under normal circumstances, while the No. 1 plate 7 and the extrusion spring 9 move with the transmission rod 8, the No. 2 plate 24 will also move with the transmission rod 8. At this time, the extrusion spring 9 will push the outer shell 10 and move with the two outer slide bars 11 and the two outer slide grooves 25 as tracks. While the outer shell 10 moves, it will drive the rotating assembly below the other end to rotate, and then the shielding assembly can be opened. After that, the replacement personnel can replace the replaceable battery 12 from the opening of the storage port 26.

[0072] After the replaceable battery 12 is replaced, the output end of the electric push rod 6 is recovered, and the transmission rod 8 pulls the No. 1 plate 7 and the No. 2 plate 24 to move together. When the No. 2 plate 24 moves, it will pull the outer shell 10 from the inner wall of the outer shell 10 toward the direction of the electric push rod 6; similarly, if the protective component is displaced before this, when the No. 2 plate 24 moves, it will also pull the protective component tightly back to the inside of the outer shell 10 through the pull rope 30, so that the two terminals of the replaceable battery 12 located inside the protective component can normally contact the two robot contact terminals 23 and form an effective circuit.

[0073] In an emergency, when the replaceable battery 12 needs to be ejected, the outer shell 10, the second board 24 and other components are all carried out according to the above steps, but at a faster speed.

[0074] It should be noted that: the contact between the two terminals of the replaceable battery 12 and the two robot contact terminals 23 is a common power supply method in the prior art, so it will not be described in detail here.

[0075] As a preferred embodiment of the present invention, the rotating assembly includes a rack 14, a gear 16, a No. 1 rotating rod 15, a No. 2 rotating rod 20, a chain 18 and two sprockets 17. One end of the No. 1 rotating rod 15 and the No. 2 rotating rod 20 are rotatably connected to the inner wall of the storage port 26. The other end of the No. 1 rotating rod 15 passes through one of the sprockets 17 and the gear 16, and is fixedly connected to the inner walls of the passed sprocket 17 and the gear 16. The other end of the No. 2 rotating rod 20 passes through another sprocket 17 and a shielding assembly, and is fixedly connected to the inner wall of the passed sprocket 17. The chain 18 is sleeved on the outer walls of the two sprockets 17, and the chain 18 is meshed with the two sprockets 17. The plane of the rack 14 is fixedly connected to the bottom surface of the outer shell 10, and the tooth surface of the rack 14 is meshed with the gear 16.

[0076] More specifically, by providing a rotating assembly, the shielding assembly can be automatically controlled to rotate while the moving assembly moves, thereby achieving the opening and sealing of the storage port 26 without the need for additional steps.

[0077] Specifically, when the outer shell 10 moves, the rack 14 located below the outer shell 10 will move together. When the rack 14 moves, it can drive the gear 16 located outside the No. 1 rotating rod 15 to rotate through meshing. When the gear 16 rotates, it will drive the sprocket 17 connected to the No. 1 rotating rod 15 to rotate in the same direction. As this sprocket 17 rotates, the chain 18 on the surface will drive another sprocket 17 to rotate, so that the No. 2 rotating rod 20 located inside the other sprocket 17 can be rotated, and the shielding assembly connected to the No. 2 rotating rod 20 can be rotated, so that the purpose of "opening the door" and "closing the door" can be achieved.

[0078] As a preferred solution of the present invention, the shielding assembly includes an explosion-proof baffle 3 and a rotating block 13. The rotating block 13 is sleeved and fixedly connected to the outer wall of the No. 2 rotating rod 20. One side of the rotating block 13 is fixedly connected to the lower end of the explosion-proof baffle 3. The length and width of the explosion-proof baffle 3 match the length and width of the opening of the storage port 26.

[0079] More specifically, by providing a shielding component, the replaceable battery 12 can be limited and shielded from the back of the replaceable battery 12, which can not only increase the stability of the replaceable battery 12, but also prevent the replaceable battery 12 from falling from the inside of the protective component.

[0080] Specifically, when the second rotating rod 20 rotates, the rotating block 13 connected to the outside of the second rotating rod 20 starts to rotate, thereby rotating the explosion-proof baffle 3 together.

[0081] As a preferred solution of the present invention, the protective component includes an inner shell 28 and two inner slides 27, the two inner slides 27 are fixedly connected to the outer walls on both sides of the inner shell 28, and inner grooves 32 are provided on both sides of the inner wall of the outer shell 10. The outer walls of the two inner slides 27 are slidably connected to the inner walls of the two inner grooves 32, and the ends of several pull ropes 30 away from the second plate 24 are fixedly connected to the outer wall of the inner shell 28. The replaceable battery 12 is located inside the inner shell 28, and the two terminals of the inner shell 28 pass through the inner shell 28 and the outer shell 10, and match the two robot contact terminals 23. The inner wall of the inner shell 28 close to the terminal of the replaceable battery 12 is fixedly connected to the smoke sensor 37 and the temperature sensor 31.

[0082] More specifically, by providing a protective component, firstly, the replaceable battery 12 can be provided with a storage and support; secondly, when an emergency occurs to the replaceable battery 12, the instantaneous high temperature and smoke can be protected and shielded, thereby reducing the impact on the explosion-proof robot body 1.

[0083] Specifically, under normal circumstances, the inner shell 28 is received inside the outer shell 10 with two inner slide bars 27 and two inner slide grooves 32. When the outer shell 10 moves normally, the inner shell 28 will move with the outer shell 10. Because the inner shell 28 is located inside the outer shell 10, it will not collide with the explosion-proof baffle 3.

[0084] When the replaceable battery 12 experiences thermal runaway, the outer slide bar 11 of the outer shell 10 cannot move in the outer slide groove 25, but the transmission rod 8 and the second plate 24 are still moving normally. At this time, the second plate 24 will push the inner shell 28 outward. At this time, the two inner slide bars 27 will move in the two inner slide grooves 32. Because of the fast speed, it will provide an inertia for the internal replaceable battery 12. Therefore, when the inner slide bar 27 moves to the bottom of the inner slide groove 32 and cannot move further, the replaceable battery 12 will continue to slide outward, and then can slide from the inner shell 28 to the outside of the explosion-proof battery compartment 2.

[0085] As a preferred solution of the present invention, extrusion openings 29 are provided on both sides of the inner shell 28, and inclined grooves 35 are provided on the upper and bottom surfaces of the two extrusion openings 29. An extrusion assembly is provided at the connection between the extrusion openings 29 and the two inclined grooves 35, and the adjacent sides of the two extrusion assemblies are respectively abutted against the two sides of the outer wall of the replaceable battery 12, and the sides of the two extrusion assemblies away from each other are connected to the outer shell 10.

[0086] More specifically, because the replaceable battery 12 is located in the inner shell 28, it is very likely to shake during the walking of the explosion-proof robot body 1, resulting in poor contact; at this time, by providing the extrusion port 29, the inclined groove 35 and the extrusion assembly, the replaceable battery 12 can be squeezed tightly inside the inner shell 28 by the extrusion assembly when the inner shell 28 is received inside the outer shell 10, but because of the effect of the inclined groove 35, as the outer shell 10 stops moving and the inner shell 28 continues to move outward, the extrusion limit of the replaceable battery 12 inside the inner shell 28 can be gradually loosened, so that the replaceable battery 12 can be limited when installing the replaceable battery 12, and the movement of the replaceable battery 12 will not be hindered when the replaceable battery 12 needs to be replaced or ejected.

[0087] As a preferred embodiment of the present invention, the extrusion assembly includes an extrusion block 19, a roller 34, a fixed block 33 and two movable rods 36. The two movable rods 36 are respectively fixedly connected to the upper surface and the bottom surface of the extrusion block 19. The outer walls of the two movable rods 36 are respectively slidably connected to the inner walls of the two inclined grooves 35. The outer wall of the extrusion block 19 is slidably connected to the inner wall of the extrusion port 29. One side of the extrusion block 19 is abutted against the side wall of the replaceable battery 12. The extrusion block 19 is sleeved and slidably connected to the outer wall of the roller 34. The other end of the roller 34 is fixedly connected to one end of the fixed block 33. The other end of the fixed block 33 is fixedly connected to the inner wall of the outer shell 10.

[0088] More specifically, when the inner shell 28 is installed inside the outer shell 10, as the inner shell 28 moves toward the inside of the outer shell 10 under the action of the pull rope 30, the extrusion block 19 will move in an "oblique" manner under the action of the two moving rods 36, and because the closer the inclined groove 35 is to the electric push rod 6, the farther it is from the replaceable battery 12, the replaceable battery 12 can be squeezed from the side wall of the replaceable battery 12 by the extrusion block 19; similarly, when the outer shell 10 remains stationary and the inner shell 28 moves toward the explosion-proof baffle 3, the extrusion block 19 will move further and further away from the replaceable battery 12, thereby canceling the extrusion limit on the replaceable battery 12.

[0089] The present invention also provides a wheeled inspection robot, comprising an explosion-proof robot body 1 and any one of the above-mentioned explosion-proof structures, a connecting cavity 4 is opened on one side of the tail of the explosion-proof robot body 1, a plurality of power cavities 5 are opened on the side of the connecting cavity 4 close to the explosion-proof robot body 1, the outer wall of the explosion-proof battery compartment 2 is fixedly connected to the inner wall of the connecting cavity 4, a plurality of electric push rods 6 are respectively located in the plurality of power cavities 5, and the plurality of electric push rods 6, two robot contact terminals 23, a smoke sensor 37 and a temperature sensor 31 are all electrically connected to the internal controller of the explosion-proof robot body 1.

[0090] More specifically, by providing the connection chamber 4 and the power chamber 5, the explosion-proof battery compartment 2 and the electric push rod 6 can be accommodated.

[0091] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
