Description

Technical Field

[0001] This application relates to the technical field of intelligent robots, and in particular to an explosion-proof early warning robot. Background Technology

[0002] Explosion-proof robots are industrial robots controlled by wireless remote control technology. Their main purpose is to replace humans in high-risk, high-intensity, and confined space equipment safety inspections in fields such as petrochemicals, flammable and explosive materials, and radioactive chemicals. They feature all-weather, uninterrupted operation, vulnerability detection, and high-risk early warning, making them a type of safe and intelligent inspection equipment.

[0003] A search revealed Chinese Patent Publication No. CN114347049B, which discloses an explosion-proof robot comprising: an explosion-proof housing, a reinforced steel plate, and a reinforced rear cover. The reinforced steel plate is movably engaged with the top of the explosion-proof housing. One end of the reinforced steel plate's lower surface is fixedly connected to the top of a connecting plate. The bottom end of the connecting plate is movably hinged to the inside of the explosion-proof housing. A U-shaped connecting frame is slidably connected to the upper outer surface of the explosion-proof housing. An L-shaped locking strip is fixedly connected to the top of the U-shaped connecting frame, and the L-shaped locking strip is movably engaged with the explosion-proof housing. An adjusting screw is threadedly connected to the middle of the U-shaped connecting frame, and a drive gear is fixedly sleeved on the middle outer surface of the adjusting screw. A U-shaped frame is slidably connected to the inner wall of the explosion-proof housing, and the top of the U-shaped frame is movably engaged with the reinforced steel plate. The U-shaped frame meshes with the drive gear via a transmission rack. This explosion-proof robot facilitates on-site repair in case of malfunctions and effectively protects integrated circuit boards in the event of a battery explosion.

[0004] Regarding the aforementioned technologies, the inventors discovered the following drawbacks: During equipment maintenance, it is necessary to first unscrew the bolts on the reinforced back cover, then remove the reinforced back cover, then rotate the locking screw and adjusting screw in sequence, and then lift the reinforced steel plate using the pull ring to detach the integrated circuit board from the inside of the explosion-proof housing. Finally, the integrated circuit board and battery can only be maintained by rotating the support frame and supporting it on the ground. The operation steps are cumbersome, making robot maintenance troublesome, and therefore improvements are needed. Summary of the Invention

[0005] In order to effectively protect the battery and integrated circuit board and facilitate the overall maintenance of the robot, this application provides an explosion-proof early warning robot.

[0006] The explosion-proof early warning robot provided in this application adopts the following technical solution: An explosion-proof early warning robot includes an explosion-proof shell, an integrated circuit board and a battery. The explosion-proof shell is provided with rollers and an inspection unit. The top of the explosion-proof shell has an opening and is provided with an end cap for controlling the opening and closing. The explosion-proof shell is vertically connected with a first sliding plate and a second sliding plate arranged sequentially from top to bottom.

[0007] The upper surface of the first slide plate is rotatably connected to a mounting plate that can be flipped in a vertical plane, and the integrated circuit board is mounted on the mounting plate;

[0008] The first sliding plate and the mounting plate are connected together by the same first connecting rope at opposite ends. The middle part of the first connecting rope passes around the first sliding seat located inside the explosion-proof housing. The first sliding seat slides horizontally and is connected to the end cover. The sliding direction of the first sliding seat is parallel to the flipping plane of the mounting plate.

[0009] The upper surface of the second slide plate is rotatably connected to an explosion-proof plate that can be flipped in the vertical plane. When the explosion-proof plate touches the upper surface of the second slide plate due to its own weight, the second slide plate and the explosion-proof plate will jointly divide the interior of the explosion-proof shell into two cavities, with the integrated circuit board and the battery respectively located in the upper and lower cavities.

[0010] The second sliding plate and the lifting seat are connected together by the same second connecting rope at opposite ends. The middle part of the second connecting rope passes around the second sliding seat located inside the explosion-proof housing. The second sliding seat slides horizontally and is connected to the end cover. The sliding direction of the second sliding seat is parallel to the flipping plane of the explosion-proof plate.

[0011] Optionally, a lifting seat located below the second sliding plate is slidably connected inside the explosion-proof housing along the vertical direction, and the battery is located on the lifting seat;

[0012] The lifting platform is connected to the end cap via a third connecting rope, and the edge of the explosion-proof plate is provided with a clearance groove for the third connecting rope to slide through.

[0013] Optionally, the first sliding plate is provided with a first limiting plate for the mounting plate to flip upward and abut against it, and the second sliding plate is provided with a second limiting plate for the explosion-proof plate to flip upward and abut against it.

[0014] When the battery rises to the top of the explosion-proof enclosure, the mounting plate will abut against the first limiting plate, and the explosion-proof plate will abut against the second limiting plate.

[0015] Optionally, the lower surface of the end cap is provided with a first pressing block and a second pressing block;

[0016] When the end cap is fastened into the opening of the explosion-proof shell, the first pressure block will press the mounting plate firmly against the upper surface of the first sliding plate, and the second pressure block will press the explosion-proof plate firmly against the upper surface of the second sliding plate.

[0017] Optionally, both the lower surface of the mounting plate and the lower surface of the explosion-proof plate are provided with reinforcing ribs.

[0018] Optionally, the inspection unit includes a battery-powered camera, a lighting fixture, a gas concentration detector, and a processor;

[0019] The upper surface of the explosion-proof enclosure is provided with four receiving cavities, and an electric cylinder is installed in each cavity. The piston rod of the electric cylinder extends vertically and is connected to a camera, a lighting lamp, a gas concentration detector, or a processor.

[0020] The receiving cavity is connected to the lower cavity of the explosion-proof shell through a wire channel.

[0021] Optionally, a cover plate that can be flipped in a vertical plane is rotatably connected to the opening of the receiving cavity, and the cover plate is connected to the cavity wall of the receiving cavity by a torsion spring;

[0022] When the inspection unit rises and disengages from the receiving cavity, it will push the cover plate to flip upward, causing the torsion spring to deform.

[0023] When the torsion spring is in its natural state, the cover plate will close the opening of the receiving cavity.

[0024] Optionally, the upper surface of the explosion-proof shell is provided with several sliding grooves, and a sliding rod is slidably embedded in the sliding grooves along the vertical direction, and the sliding rod is connected to the end cap;

[0025] The slide bar is threaded with a vertically arranged screw. The screw rotates around its own axis and is connected to the explosion-proof housing. The lower end of the screw extends to the bottom of the explosion-proof housing and is fixedly fitted with a synchronous pulley. All synchronous pulleys are fitted with the same synchronous belt.

[0026] Optionally, the opening of the explosion-proof housing is stepped, and the end cap can be recessed into the opening so that the upper surface of the end cap is flush with the upper surface of the explosion-proof housing.

[0027] In summary, this application includes the following beneficial technical effects:

[0028] 1. When the inspection robot is about to cause danger, the command center can send a signal through the processor to cause the electric cylinder to drive the inspection unit to descend and sink into the receiving cavity. The torsion spring will cause the cover plate to close the opening of the receiving cavity, so that the inspection unit is sealed in the receiving cavity. The explosion-proof shell will effectively protect the inspection unit, and the camera can continue to monitor through the high-strength transparent glass on the explosion-proof shell.

[0029] 2. In the event of an explosion, the explosion-proof plate will separate the integrated circuit board and the battery inside the explosion-proof enclosure, thereby effectively protecting the integrated circuit board when the battery explodes;

[0030] 3. When it is necessary to repair the integrated circuit board and the battery, the worker will rotate the handle so that the screw drives the end cover to rise through the slide rod. At this time, the mounting plate flips to the upper left and abuts against the first limit plate, and the explosion-proof plate flips to the upper right and abuts against the second limit plate. The battery rises to the top opening of the explosion-proof shell. At this time, the integrated circuit board and the battery can be repaired. The operation is convenient.

[0031] 4. After the integrated circuit board and battery have been repaired, the worker will rotate the handle in the opposite direction, causing the screw to slide down and sink into the explosion-proof enclosure through the slide rod. The lifting seat, battery, second slide plate, first slide plate, mounting plate, integrated circuit board and explosion-proof plate will reset due to their own weight, so that the integrated circuit board and battery are stored in the explosion-proof enclosure.

[0041] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0042] This application discloses an explosion-proof early warning robot. For example... Figure 1 As shown, an explosion-proof early warning robot includes an explosion-proof shell 1 with the opening 11 facing upwards. Four rollers 12 are installed at the bottom of the explosion-proof shell 1, and an inspection unit 2 is provided at the top of the explosion-proof shell 1, enabling the robot to perform inspections and explosion-proof early warnings during movement.

[0043] like Figure 2 As shown, the explosion-proof housing 1 has an integrated circuit board 3 and a storage battery 4 inside. An end cap 13 is provided at the opening 11 of the explosion-proof housing 1. The end cap 13 can control the opening and closing of the opening 11, so as to effectively protect the integrated circuit board 3 and the storage battery 4, and facilitate the maintenance of the integrated circuit board 3 and the storage battery 4.

[0044] The opening 11 of the explosion-proof housing 1 is stepped, and the end cap 13 can be recessed into the opening 11, so that the upper surface of the end cap 13 is flush with the upper surface of the explosion-proof housing 1, avoiding the side of the end cap 13 from being exposed to the outside of the explosion-proof housing 1, making the connection between the end cap 13 and the explosion-proof housing 1 more tight, thereby improving the overall explosion-proof effect of this application.

[0045] like Figure 1 and Figure 3 As shown, the inspection unit 2 includes a camera 21, a lighting lamp 22, a gas concentration detector, and a processor 24, which are respectively located at the four corners of the explosion-proof housing 1. Each of the four corners of the upper surface of the explosion-proof housing 1 is provided with a receiving cavity 14. A vertically arranged electric cylinder 141 is installed on the bottom cavity wall of the receiving cavity 14. The piston rod of the electric cylinder 141 extends vertically and is connected to the camera 21, the lighting lamp 22, the gas concentration detector, or the processor 24.

[0046] By using the electric cylinder 141 to raise the inspection unit 2 above the explosion-proof housing 1, the inspection unit 2 can perform inspections and explosion-proof warnings. By using the electric cylinder 141 to lower the inspection unit 2 into the receiving cavity 14, the explosion-proof housing 1 can effectively protect the inspection unit 2. Furthermore, by storing the inspection unit 2 in the receiving cavity 14, the overall volume of this application is reduced, which facilitates the loading and transportation of this application.

[0047] It is worth noting that the explosion-proof housing 1 located at the camera 21 can be made of high-strength transparent glass, so that the camera 21, which is housed in the housing cavity 14, can still detect the external situation in a timely manner.

[0048] The receiving cavity 14 is connected to the lower part of the explosion-proof housing 1 through a wire channel. The wires on the electric cylinder 141 and the inspection unit 2 can pass through the wire channel and be connected to the battery 4 so that the battery 4 can supply power to the electric cylinder 141 and the inspection unit 2. The wires are hidden inside the explosion-proof housing 1, thus effectively protecting the wires.

[0049] A fixed housing 142 is installed on the top of the piston rod of the electric cylinder 141. The camera 21, the lighting lamp 22, the gas concentration detector and the processor 24 are all installed in the corresponding fixed housing 142. One side of the fixed housing 142 is open to allow the camera 21, the lighting lamp 22, the gas concentration detector and the processor 24 to be used normally.

[0050] like Figure 3 and Figure 4 As shown, a cover plate 143 that can be flipped in the vertical plane is rotatably connected to the opening of the cavity 14 via a horizontal axis. The cover plate 143 is connected to the cavity wall of the cavity 14 via a torsion spring 144.

[0051] During the upward movement, the inspection unit 2 can push the cover plate 143 to flip upward, exposing the opening of the receiving cavity 14. At this time, the inspection unit 2 can rise and detach from the receiving cavity 14 so that the inspection unit 2 can perform inspection. At the same time, the torsion spring 144 will deform and cause the cover plate 143 to first press against the side of the fixed shell 142, and then press against the piston rod of the electric cylinder 141. The side of the fixed shell 142 pressed by the cover plate 143 is flush with the side of the piston rod of the electric cylinder 141 pressed by the cover plate 143, so that the cover plate 143 can move back and forth on the fixed shell 142 and the piston rod of the electric cylinder 141.

[0052] When the electric cylinder 141 drives the inspection unit 2 to descend and sink into the receiving cavity 14 through the fixed shell 142, the torsion spring 144 will return to its natural state and cause the cover plate 143 to re-close the opening of the receiving cavity 14, so that the inspection unit 2 is sealed in the receiving cavity 14, thereby improving the protection effect of the explosion-proof shell 1 on the inspection unit 2.

[0053] like Figure 5 As shown, the upper surface of the explosion-proof shell 1 is provided with several sliding grooves 15, and a sliding rod 151 is slidably embedded in the sliding groove 15 along the vertical direction. The upper end face of the sliding rod 151 is connected to the lower surface of the end cover 13.

[0054] The bottom of the slide rod 151 is threaded with a vertically arranged screw rod 152. The screw rod 152 is rotatably connected to the explosion-proof housing 1 around its own axis. The lower end of the screw rod 152 extends to the bottom of the explosion-proof housing 1 and is fixedly fitted with a synchronous pulley 153. All synchronous pulleys 153 are fitted with the same synchronous belt 154. A handle 155 is installed at the bottom of one of the screw rods 152.

[0055] When the worker rotates the handle 155, all the screws 152 will rotate synchronously and in the same direction under the action of the timing belt 154 and the timing pulley 153, so that the slide rod 151 drives the end cover 13 to rise and fall, so as to store and maintain the battery 4 and the integrated circuit board 3.

[0056] like Figures 6 to 8 As shown, the explosion-proof housing 1 is provided with a first sliding plate 5, a second sliding plate 6 and a lifting seat 7 arranged sequentially from top to bottom. The first sliding plate 5, the second sliding plate 6 and the lifting seat 7 are all connected to the explosion-proof housing 1 in the vertical direction through the sliding cooperation of dovetail grooves and dovetail blocks, so that the first sliding plate 5, the second sliding plate 6 and the lifting seat 7 can only perform lifting and lowering movements.

[0057] The upper surface of the first slide plate 5 is rotatably connected to a mounting plate 51 that can be flipped in a vertical plane. The integrated circuit board 3 is mounted on the mounting plate 51. The opposite ends of the first slide plate 5 and the mounting plate 51 are connected to the same first connecting rope 52. The middle part of the first connecting rope 52 passes around the first sliding seat 53 located inside the explosion-proof shell 1. The first sliding seat 53 slides horizontally and is connected to the end cover 13. The sliding direction of the first sliding seat 53 is parallel to the flipping plane of the mounting plate 51.

[0058] During the rising process of the end cover 13, the end cover 13 will pull the first slide plate 5 and the mounting plate 51 upward through the first connecting rope 52. When the first slide plate 5 rises to the highest point of its movement trajectory, the first slide plate 5 will remain stationary, while the end of the mounting plate 51 connected by the first connecting rope 52 will flip upward, and the first sliding seat 53 will slide closer to the first slide plate 5, so that the mounting plate 51 and the integrated circuit board 3 can gradually flip upward and detach from the inside of the explosion-proof shell 1 for the maintenance of the integrated circuit board 3.

[0059] The upper surface of the second sliding plate 6 is rotatably connected to an explosion-proof plate 61 that can flip in a vertical plane. The flipping plane of the explosion-proof plate 61 is parallel to the flipping plane of the mounting plate 51. When the explosion-proof plate 61 presses against the upper surface of the second sliding plate 6 due to its own weight, the second sliding plate 6 and the explosion-proof plate 61 together divide the interior of the explosion-proof shell 1 into upper and lower cavities. The integrated circuit board 3 and the battery 4 are respectively located in the upper and lower cavities. That is, the explosion-proof plate 61 will separate the integrated circuit board 3 and the battery 4, thereby effectively protecting the integrated circuit board 3 when the battery 4 explodes.

[0060] The second sliding plate 6 and the lifting seat 7 are connected together by the same second connecting rope 62 at opposite ends. The middle part of the second connecting rope 62 passes around the second sliding seat 63 located inside the explosion-proof shell 1. The second sliding seat 63 slides horizontally and is connected to the end cover 13. The sliding direction of the second sliding seat 63 is parallel to the flipping plane of the explosion-proof plate 61.

[0061] During the rising process of end cap 13, end cap 13 will pull the second slide plate 6 and explosion-proof plate 61 upward through the second connecting rope 62; when the second slide plate 6 rises to the highest point of its movement trajectory, the second slide plate 6 will remain stationary, while the end of explosion-proof plate 61 connected by the second connecting rope 62 will flip upward, and the second sliding seat 63 will slide closer to the second slide plate 6, so that the explosion-proof plate 61 can gradually flip upward and detach from the inside of the explosion-proof shell 1, so that the explosion-proof plate 61 will no longer block the battery 4, so that the battery 4 can be inspected.

[0062] It is worth noting that the first sliding plate 5 and the second sliding plate 6 are respectively located on the left and right sides of the explosion-proof housing 1, so that the mounting plate 51 and the explosion-proof plate 61, which are flipped and detached from the inside of the explosion-proof housing 1, can be respectively located on the left and right sides of the explosion-proof plate 61, so as to prevent the explosion-proof plate 61 from blocking the workers from inspecting the integrated circuit board 3.

[0063] Both the first sliding seat 53 and the second sliding seat 63 are composed of a dovetail block and a guide wheel rotatably connected to the dovetail block. The dovetail block is slidably fitted into a dovetail groove provided on the lower surface of the end cover 13, and the guide wheel is for the middle part of the first connecting rope 52 or the second connecting rope 62 to pass around.

[0064] The upper surface of the lifting seat 7 is connected to the lower surface of the end cover 13 by four third connecting ropes 71. The edge of the explosion-proof plate 61 is provided with a clearance groove 611 for two of the third connecting ropes 71 to slide through. The second sliding plate 6 is provided with a clearance groove 611 for the other two third connecting ropes 71 to slide through.

[0065] The upper surface of the first sliding plate 5 is equipped with a first limiting plate 54 that is inclined, and the second sliding plate 6 is equipped with a second limiting plate 64 that is inclined.

[0066] During the lifting process of the end cover 13, the end cover 13 will pull the first slide plate 5 and the mounting plate 51 upward through the first connecting rope 52, so that the mounting plate 51 flips to the upper left and abuts against the first limiting plate 54, so as to facilitate the maintenance of the integrated circuit board 3; the end cover 13 will also pull the second slide plate 6 and the explosion-proof plate 61 upward through the second connecting rope 62, so that the explosion-proof plate 61 flips to the upper right and abuts against the second limiting plate 64, so that the explosion-proof plate 61 no longer blocks the battery 4; the end cover 13 will then pull the lifting seat 7 and the battery 4 upward through the third connecting rope 71, so that the battery 4 rises to the top opening 11 of the explosion-proof shell 1, so as to facilitate the maintenance of the battery 4.

[0067] like Figure 2 and Figure 7As shown, a plurality of first pressing blocks 131 and a plurality of second pressing blocks 132 are installed on the lower surface of the end cap 13. When the end cap 13 is fastened to the opening 11 of the explosion-proof shell 1, the first pressing blocks 131 will press the mounting plate 51 against the upper surface of the first sliding plate 5, so that the integrated circuit board 3 remains stable inside the explosion-proof shell 1 to prevent the integrated circuit board 3 from being damaged by collision; the second pressing blocks 132 will press the explosion-proof plate 61 against the upper surface of the second sliding plate 6, so that the explosion-proof plate 61 remains stable inside the explosion-proof shell 1 to ensure the separation of the integrated circuit board 3 and the battery 4 by the explosion-proof plate 61.

[0068] The lower surfaces of the mounting plate 51 and the explosion-proof plate 61 are integrally formed with several reinforcing ribs 511, which increases the structural strength of the mounting plate 51 and the explosion-proof plate 61.

[0069] The implementation principle of an explosion-proof early warning robot according to an embodiment of this application is as follows: During robot inspection, camera 21, lighting 22, gas concentration detector and processor 24 are located above explosion-proof housing 1. Camera 21 monitors the interior of the area in real time, lighting 22 is used to illuminate the inspection area, gas concentration detector is used to detect the gas concentration in the inspection area, processor 24 is used to receive signals and control the actions of camera 21 and lighting 22, and processor 24 can receive alarm signals from gas concentration detector and feed them back to the command center.

[0070] When the inspection robot is about to cause danger, the command center can send a signal through the processor 24, causing the electric cylinder 141 to drive the inspection unit 2 to descend and sink into the receiving cavity 14. The torsion spring 144 will cause the cover plate 143 to close the opening of the receiving cavity 14, so that the inspection unit 2 is sealed in the receiving cavity 14. The explosion-proof shell 1 will effectively protect the inspection unit 2, and the camera 21 can continue to monitor through the high-strength transparent glass on the explosion-proof shell 1.

[0071] In the event of an explosion, the cooperation of the explosion-proof housing 1, screw 152, and slide bar 151 ensures that the end cap 13 is stably sealed within the opening 11 of the explosion-proof housing 1. The first pressure block 131 presses the mounting plate 51 against the upper surface of the first sliding plate 5, and the second pressure block 132 presses the explosion-proof plate 61 against the upper surface of the second sliding plate 6. The explosion-proof plate 61 separates the integrated circuit board 3 and the battery 4 inside the explosion-proof housing 1, thereby effectively protecting the integrated circuit board 3 when the battery 4 explodes.

[0072] When the integrated circuit board 3 and the battery 4 need to be repaired, the worker will rotate the handle 155, causing the screw 152 to drive the end cover 13 to rise through the slide rod 151. The end cover 13 will then pull the first slide plate 5 and the mounting plate 51 to rise through the first connecting rope 52, causing the mounting plate 51 to flip to the upper left and abut against the first limiting plate 54. The end cover 13 will also pull the second slide plate 6 and the explosion-proof plate 61 to rise through the second connecting rope 62, causing the explosion-proof plate 61 to flip to the upper right and abut against the second limiting plate 64. The end cover 13 will then pull the lifting seat 7 and the battery 4 to rise through the third connecting rope 71, causing the battery 4 to rise to the top opening 11 of the explosion-proof shell 1. At this time, the integrated circuit board 3 and the battery 4 can be repaired, which is convenient to operate.

[0073] After the integrated circuit board 3 and the battery 4 are repaired, the worker will rotate the handle 155 in the opposite direction, so that the screw 152 drives the end cover 13 to descend and sink into the opening 11 of the explosion-proof housing 1 through the slide rod 151. The lifting seat 7, the battery 4, the second slide plate 6 and the first slide plate 5 will sink and reset due to their own weight. The mounting plate 51, the integrated circuit board 3 and the explosion-proof plate 61 will flip downward and reset due to their own weight, so that the integrated circuit board 3 and the battery 4 are stored in the explosion-proof housing 1.

[0074] In summary, by rotating the handle 155, the integrated circuit board 3 and the battery 4 can be moved in and out of the explosion-proof housing 1, which facilitates the storage and maintenance of the integrated circuit board 3 and the battery 4. At the same time, when the integrated circuit board 3 and the battery 4 are stored inside the explosion-proof housing 1, they are separated by the explosion-proof plate 61, which effectively protects the battery 4 and the integrated circuit board 3.

[0075] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
