[0016] 1. Through the obstacle removal mechanism, the motor starts to drive the support seat to rotate, and then the support seat rotates to facilitate the obstacle removal mechanism to rotate and adjust the direction. The first support arm and the second support arm are controlled by the telescopic movement of the cylinder output end, and then the cross plate is moved to the front of the obstacle. The fireproof cover provides protection for the second motor, and then the second motor starts to drive the threaded rod to rotate. Since the two sets of threads on the outside of the threaded rod are opposite, when the threaded rod rotates, the two clamps move in the opposite direction along the slide rod to clamp the obstacle. Then the obstacle is moved away by the rotation of the obstacle removal mechanism, and the bucket is used to improve the efficiency of obstacle removal.

[0017] 2. Through the buffer mechanism, when collapsed objects or falling objects hit the robot, they will fall onto the elastic steel plate. The elastic steel plate will bend under pressure to compress the second spring so that the second spring is compressed to achieve buffering. At the same time, the elastic steel plate will force the two sliders to retreat after being compressed. When the slider retreats, it moves along the round rod and compresses the third spring, which is beneficial to compress the third spring to achieve buffering. At the same time, when the slider moves, it moves with the slide plate, and then the inclined groove moves outside the plug block. At this time, the conduction rod slides downward inside the support block, and then the bottom of the conduction rod contacts the ground, which is beneficial to transfer the pressure to the ground to achieve further buffering. The buffer mechanism can protect the robot when collapsed objects or falling objects hit the robot.

[0018] 3. The infrared night vision device can accurately see the situation at the fire scene where visibility is almost zero. The image seen by the infrared night vision device is transmitted to the display screen of the remote control that controls the robot. The remote control is controlled by the on-site supervisor of the fire brigade. The navigation and positioning module plans a safe route for the robot to walk through thick smoke. The anti-collision module improves the safety of the robot walking at the fire scene. The life detector can identify people with vital signs in the thick smoke. The trapped people open the box cover and take out the dry powder fire extinguisher, and then use the dry powder fire extinguisher to spray out the surrounding fire to create a short escape route.

The following is an explanation of its embodiments based on the overall structure of the present invention.

[0031] A chemical park fire rescue robot, comprising: a robot 1, the robot 1 comprising an obstacle clearing mechanism 2, a fixing mechanism 3, and a buffer mechanism 4, the obstacle clearing mechanism 2 being arranged in front of the robot 1, the buffer mechanism 4 being arranged on the top of the robot 1, an infrared night vision device 17 being installed in front of the robot 1, the infrared night vision device 17 being able to accurately see the on-site conditions at a fire scene where visibility is almost zero, a speaker 20 being arranged in front of the robot 1, the speaker 20 being used for the robot 1 to make sounds, the robot 1 being a crawler structure capable of The robot 1 can climb stairs and collapsed objects at the fire scene so that it will not be unable to move forward due to the terrain at the fire scene. The material of the robot 1 is fire-proof steel that can withstand temperatures of thousands of degrees. The abdominal cavity of the robot 1 is provided with a first chamber 5, a second chamber 6, and a third chamber 7. A first motor 8 is fixed inside the first chamber 5, and a fire helmet and fireproof clothing are stored inside the first chamber 5. Oxygen is stored inside the fireproof helmet and an oxygen mask is installed. The third chamber 7 is used to carry seriously injured or unconscious persons, and oxygen is stored inside the third chamber 7.

[0032] Furthermore, the obstacle clearing mechanism 2 includes a support base 201 rotatably connected to the top of the robot 1, the output end of the first motor 8 passes through the top of the robot 1 and is fixedly connected to the center of the bottom of the support base 201, one side of the support base 201 is rotatably connected to a first support arm 202, the top of the support base 201 is rotatably connected to a first cylinder 203, the output end of the first cylinder 203 is rotatably connected to the first support arm 202, one end of the first support arm 202 is rotatably connected to the second support arm 204, the interior of the first support arm 202 is rotatably connected to the second cylinder 203, the output end of the second cylinder 203 is rotatably connected to the second support arm 204, the first motor 8 is started to drive the support base 201 to rotate, and then the support base 201 rotates to facilitate the obstacle clearing mechanism 2 to rotate and adjust the direction, the first support arm 202 and the second support arm 204 are controlled to move by the extension and retraction of the output end of the cylinder 203, and then the cross plate 205 is moved to the front of the obstacle.

[0033] Furthermore, a transverse plate 205 is fixed to one end of the second support arm 204, and a threaded rod 206 is rotatably connected to the bottom of the transverse plate 205, and two sets of opposite threads are arranged on the outside of the threaded rod 206. A fireproof cover 207 is fixed to one end of the transverse plate 205, and a second motor 208 is installed inside the fireproof cover 207. The output end of the second motor 208 is fixedly connected to one end of the threaded rod 206. Two sliding rods 209 are fixed to the bottom of the transverse plate 205, and two clamping plates 210 are slidably connected to the outside of the two sliding rods 209. The threaded rod 206 penetrates the two clamping plates 210 and is rotatably connected to the two clamping plates 210. A bucket 211 is arranged directly in front of the robot 1.

[0034] Next, a vertical groove is provided at one end of the third chamber 7, and an electromagnetic slide rail 21 is installed inside the vertical groove and the inside of the third chamber 7. The outside of the electromagnetic slide rail 21 is slidably connected with an electromagnetic slider 16, and the electromagnetic slider 16 in the third chamber 7 is fixed with a pad 18, and the electromagnetic slider 16 in the vertical groove is fixed with a baffle 19, and the interior of the third chamber 7 is wrapped with flexible cotton.

[0035] It should be noted that the fireproof cover 207 provides protection for the second motor 208, and then the second motor 208 is started to drive the threaded rod 206 to rotate. Since the two sets of threads on the outside of the threaded rod 206 are opposite, when the threaded rod 206 rotates, the two clamping plates 210 move in the opposite direction along the slide bar 209 to clamp the obstacle, and then the obstacle is moved away by the rotation of the obstacle removal mechanism 2, and the bucket 211 is used to improve the efficiency of obstacle removal. When the trapped person is seriously injured or unconscious, the electromagnetic slider 16 in the third chamber 7 is on the electromagnetic slide rail. The electromagnetic slider 16 in the vertical groove slides down on the outside of the electromagnetic slide rail 21, and descends with the baffle 19 to seal the third chamber 7 to protect the seriously injured or unconscious person inside.

[0036] Next, a box 9 is provided inside the second chamber 6, and a dry powder fire extinguisher 10 is stored inside the box 9. The top of the box 9 extends to the top of the robot 1. The top of the box 9 is rotatably connected to a box cover 11. The fixing mechanism 3 includes a hollow ring 301 fixed inside the box 9. The dry powder fire extinguisher 10 is placed inside the hollow ring 301. The fixing mechanism 3 is used to fix the dry powder fire extinguisher 10 to prevent the dry powder fire extinguisher 10 from hitting the box 9 when the robot 1 shakes. The hollow ring 301 is provided with an empty groove 302 inside, a first spring 303 is fixed inside the empty groove 302 and a push plate 304 is slidably connected, one end of the first spring 303 is fixedly connected to the push plate 304, one end of the push plate 304 is fixedly connected to an extension rod 305, one end of the extension rod 305 passes through the hollow ring 301 and is fixed to an arc plate 306, a rope 307 is fixed to the push plate 304, and the top end of the rope 307 is fixedly connected to the bottom of the box cover 11.

[0037] It can be concluded that the robot needs to open the box cover 11 before entering the fire scene. The box cover 11 is opened by rotation and the rope 307 will be pulled when the box cover 11 is opened. When the rope 307 is pulled, the first spring 303 is compressed and then the push plate 304 retreats inside the empty slot 302. When the push plate 304 retreats, it retreats with the arc plate 306 through the extension rod 305, and then the dry powder fire extinguisher 10 is placed inside the hollow ring 301, and then the box cover 11 is reset. At this time, the rope 307 is loosened and the first spring 303 is reset, and then the push plate 304, the extension rod 305 and the arc plate 306 are reset, and then the arc plate 306 pushes the dry powder fire extinguisher 10 against the inside of the hollow ring 301. When the robot 1 shakes, it can prevent the dry powder fire extinguisher 10 from hitting the box 9 and causing damage, and protect the dry powder fire extinguisher 10 by limiting and fixing it.

[0038] In addition, a navigation and positioning module 12 and an anti-collision module 13 are installed inside the second chamber 6. The navigation and positioning module 12 plans a safe route for the robot 1 to walk in thick smoke. The anti-collision module 13 improves the safety of the robot 1 walking in a fire scene and prevents it from directly colliding with a building. A life detector 14 is placed inside the second chamber 6. The life detector 14 can find people with vital signs in thick smoke. A controller 15 is set inside the second chamber 6. All electrical components of the robot 1 are controlled by the controller 15.

[0039] It needs to be explained that the infrared night vision device 17 can accurately see the situation at the fire scene where visibility is almost zero. The picture seen by the infrared night vision device 17 is transmitted to the display screen of the remote control that controls the robot 1. The remote control is controlled by the on-site supervisor of the fire brigade. The navigation and positioning module 12 plans a safe route for the robot 1 to walk in the thick smoke. The anti-collision module 13 improves the safety of the robot 1 walking in the fire scene. The life detector 14 can identify people with vital signs in the thick smoke. When the robot 1 determines the position of the trapped person, it drives to the trapped person, and then the on-site supervisor of the fire brigade controls the lock of the first compartment 5 to open through the remote control, and then the trapped person takes out the fire helmet and fireproof clothing in the first compartment 5 and quickly puts them on.

[0040] In addition, the buffer mechanism 4 includes a slide groove 401 set on the top of the robot 1, the inside of the slide groove 401 is fixed with a round rod 402, the outside of the round rod 402 is slidably connected with an arc-shaped elastic steel plate 403, the inside of the slide groove 401 is fixed with a second spring 404, the top of the second spring 404 is fixedly connected with the bottom of the elastic steel plate 403, the outside of the slide groove 401 is slidably connected with a slider 405 and the slider 405 passes through the round rod 402, and the two ends of the slide groove 401 are fixed with third springs 406, the third The spring 406 is located outside the round rod 402, and the side wall of the robot 1 is provided with a limit groove 407, and the robot 1 is slidably connected with a slide plate 408 along the limit groove 407, one side of the slider 405 is fixedly connected to the top of the slide plate 408, and the slide plate 408 is provided with an inclined groove 409, and a support block 410 is fixed to the side wall of the robot 1, and a conduction rod 411 is slidably connected inside the support block 410, and an insert block 412 is fixed to the top of the conduction rod 411, and the rear end of the insert block 412 is located inside the inclined groove 409.

[0041] Specifically, when a collapsed object or a falling object hits the robot 1, it will fall onto the elastic steel plate 403. The elastic steel plate 403 is compressed and bent to compress the second spring 404, so that the second spring 404 is compressed to achieve buffering. At the same time, the elastic steel plate 403 is compressed to force the two sliders 405 to retreat. When the slider 405 retreats, it moves along the round rod 402 and compresses the third spring 406, which is beneficial to compress the third spring 406 to achieve buffering. At the same time, when the slider 405 moves, it moves with the slide plate 408, and then the inclined groove 409 moves outside the insertion block 412. At this time, the conduction rod 411 slides downward inside the support block 410, and then the bottom of the conduction rod 411 contacts the ground, which is beneficial to transfer the pressure to the ground to achieve further buffering. The buffer mechanism 4 set can protect the robot 1 when collapsed objects or falling objects hit the robot 1.

[0042] Working principle: through the obstacle clearing mechanism 2, the first motor 8 is started to drive the support seat 201 to rotate, and then the support seat 201 rotates to facilitate the obstacle clearing mechanism 2 to rotate and adjust the direction, and the first support arm 202 and the second support arm 204 are controlled to move by the extension and contraction of the output end of the cylinder 203, and then the cross plate 205 is moved to the front of the obstacle, and the fireproof cover 207 provides protection for the second motor 208, and then the second motor 208 is started to drive the threaded rod 206 to rotate. Since the two sets of threads on the outside of the threaded rod 206 are opposite, when the threaded rod 206 rotates, the two clamping plates 210 move in the opposite direction along the sliding rod 209 to clamp the obstacle, and then the obstacle is moved away by the rotation of the obstacle clearing mechanism 2, and at the same time, the bucket 211 is used to improve the efficiency of obstacle clearing. When the trapped persons are seriously injured or unconscious, the electromagnetic slider 16 in the third chamber 7 moves outside the electromagnetic slide rail 21 and extends out from the inside of the third chamber 7 with the pad 18, and then the obstacle removal mechanism 2 rotates to the front of the seriously injured or unconscious person, and then the two clamps 210 move in the opposite direction to clamp the seriously injured or unconscious person and place it on the top of the pad 18, and then the pad 18 retracts into the inside of the third chamber 7. The inside of the third chamber 7 is equipped with oxygen for breathing, and the electromagnetic slider 16 in the vertical groove slides and descends outside the electromagnetic slide rail 21, and descends with the baffle 19 to block the third chamber 7 to protect the seriously injured and unconscious persons inside. The obstacle removal mechanism 2 can not only remove obstacles but also place the seriously injured and unconscious persons on the pad 18 to play a role in rescue.

[0043] By setting the fixing mechanism 3, the robot needs to open the box cover 11 before entering the fire scene. The box cover 11 is opened by rotation and the rope 307 is pulled when the box cover 11 is opened. When the rope 307 is pulled, the first spring 303 is compressed and the push plate 304 retreats inside the empty slot 302. When the push plate 304 retreats, the arc plate 306 retreats through the extension rod 305, and then the dry powder fire extinguisher 10 is placed inside the hollow ring 301, and then the box cover 11 is reset. At this time, the rope 307 is released and the first spring 303 is reset, then the push plate 304, the extension rod 305 and the arc plate 306 are reset, and then the arc plate 306 pushes the dry powder fire extinguisher 10 against the inside of the hollow ring 301, and when the robot 1 shakes, it can prevent the dry powder fire extinguisher 10 from hitting the box 9 and causing damage, and the dry powder fire extinguisher 10 is protected by limiting and fixing it. In this mechanism, when the box cover 11 is opened, the dry powder fire extinguisher 10 is released, and when the box cover 11 is reset, the dry powder fire extinguisher 10 is limited and fixed.

[0044] By means of the buffer mechanism 4, when collapsed objects or falling objects hit the robot 1, they will fall onto the elastic steel plate 403, and the elastic steel plate 403 will be bent under pressure to compress the second spring 404 so that the second spring 404 is compressed to achieve buffering. At the same time, the elastic steel plate 403 will force the two sliders 405 to retreat after being compressed. When the slider 405 retreats, it moves along the round rod 402 and compresses the third spring 406, which is beneficial to compress the third spring 406 to achieve buffering. At the same time, when the slider 405 moves, it moves with the slide plate 408, and then the inclined groove 409 moves outside the plug block 412. At this time, the conduction rod 411 slides downward inside the support block 410, and then the bottom of the conduction rod 411 contacts the ground, which is beneficial to transfer the pressure to the ground to achieve further buffering. By means of the buffer mechanism 4, the robot 1 can be protected when collapsed objects or falling objects hit the robot 1.

[0045] Since the bottom of the robot 1 is a crawler structure, it can climb stairs and collapsed objects at the fire scene. At the same time, the obstacle removal mechanism 2 works to remove obstacles, so that the robot 1 will not be unable to move forward due to terrain or obstacles at the fire scene. At the same time, the material of the robot 1 is fireproof steel and can withstand high temperatures of thousands of degrees. The robot is equipped with an infrared night vision device 17, which can accurately see the situation at the fire scene with almost zero visibility. The picture seen by the infrared night vision device 17 is transmitted to the display screen of the remote control that controls the robot 1. The remote control is controlled by the on-site supervisor of the fire brigade. The navigation and positioning module 12 plans a safe route for the robot 1 to walk in thick smoke.
