Description

Technical Field

[0001] This utility model relates to the field of fire protection engineering technology, and in particular to a four-tracked fire extinguishing robot. Background Technology

[0002] With the acceleration of urbanization, fires are frequently occurring in complex scenarios such as high-rise buildings, chemical industrial parks, and underground tunnels. Traditional firefighting operations face multiple threats from high temperatures, dense smoke, toxic gases, and complex terrain. Direct entry of firefighters into the scene can easily lead to casualties. At the same time, the rapid development of robotics, automated control, and high-temperature resistant materials has provided technical support for the upgrading of firefighting equipment. By combining fire extinguishing modules, environmental perception systems, and remote control functions, firefighting equipment can replace personnel to enter high-risk fire scenes to complete tasks such as fire reconnaissance and fire extinguishing. This not only reduces the operational risks for firefighters but also makes up for the shortcomings of traditional equipment in extreme scenarios, meeting the modern firefighting demand for "unmanned, efficient, and safe" operations.

[0003] The core structure of the four-tracked firefighting robot includes a four-tracked drive chassis, a modular firefighting module, an environmental perception system, and an intelligent control unit. The perception system first collects data such as fire temperature, fire source location, and terrain in real time, and transmits it to the control unit. The autonomous navigation algorithm plans the optimal path, or the four-tracked chassis is driven to move to the work site via remote commands. Then, the control unit activates the corresponding firefighting module according to the fire type, adjusts the nozzle angle and pressure to accurately extinguish the fire source, and continuously feeds back fire data to ensure safe and efficient operation.

[0004] During equipment use, the size of the fire varies, sometimes requiring the equipment to operate for extended periods. However, the lack of a quick battery replacement function means that the equipment needs to be recharged after a certain period of operation, thus reducing its efficiency. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a four-tracked firefighting robot, which aims to improve the problem that existing equipment cannot quickly replace batteries, thus causing it to be unable to work continuously.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A four-tracked firefighting robot includes a base, the base having a quick-change mechanism inside, and a support mechanism at the bottom of the base. The quick-change mechanism includes a dustproof plate, which slides externally to the rear end of the base. A support plate is fixedly connected to the outside of the dustproof plate. A sliding strip is slidably connected to the inside of the support plate. Multiple transmission plates are rotatably connected to the outside of the sliding strip. A connecting ring is rotatably connected to the end of each transmission plate away from the sliding strip. A connecting post is fixedly connected to the outside of the connecting ring. A connecting spring is sleeved on the outside of the connecting post. A limit block is fixedly connected to the end of the connecting post away from the connecting ring. Multiple limit rings are fixedly connected to the inside of the support plate. A battery is fixedly connected to the top of the support plate. As a further description of the above technical solution: One end of the connecting spring is fixedly connected to the outside of the limiting ring, and the other end of the connecting spring is fixedly connected to the rear end of the litigation limiting block. As a further description of the above technical solution: The base has multiple limiting grooves inside, and the limiting block slides outside the limiting grooves. As a further description of the above technical solution: The outer side of the connecting column slides inside the limiting ring, the outer side of the sliding strip slides inside the dustproof plate, the top of the base is fixedly connected to a nozzle, the outer side of the base is fixedly connected to a water inlet, and the bottom of the base is fixedly connected to a track wheel. As a further description of the above technical solution: The support mechanism includes two protective shells, the bottoms of which are fixedly connected to the front and rear ends of the base, respectively. Two air pumps are fixedly connected inside each of the two protective shells. A sliding block is fixedly connected to the drive end of the air pump. A support leg is fixedly connected to the outside of the sliding block. A clearing component is provided at the bottom of the base. As a further description of the above technical solution: The obstacle clearing component includes a fixed block, the top of which is fixedly connected to the bottom of the base. Two dampers are fixedly connected inside the fixed block, and a buffer spring is sleeved on the outside of the dampers.

[0007] This utility model has the following beneficial effects: 1. In this utility model, by pressing the sliding bar, the sliding bar slides inside the support plate, thereby driving the transmission plate, which in turn drives the connecting ring to slide, so that the connecting column drives the connecting spring to move synchronously, thereby causing the limiting block to slide out of the base, and thus the support plate can drive the battery to slide out of the base.

[0008] 2. In this utility model, the push plate can be used to initially clean the ground.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Example 1: A four-tracked firefighting robot, referring to Figure 1 , Figure 2 and Figure 3 The device includes a base 1, which has a quick-change mechanism 5 inside. The quick-change mechanism 5 enables the device to work quickly and continuously. The bottom of the base 1 has a support mechanism 6, which prevents the device from moving during operation. The quick-change mechanism 5 includes a dustproof plate 50, which prevents dust from entering the base 1 and causing the battery 59 to lose power. The dustproof plate 50 slides externally at the rear end of the base 1. A support plate 51 is fixedly connected to the outside of the dustproof plate 50, which supports the battery 59. A sliding strip 52 is slidably connected inside the support plate 51. Pressing the sliding strip 52 causes the transmission plate 53 to rotate. Multiple transmission plates 53 are rotatably connected to the outside of the sliding strip 52. The left and right sides of the transmission plates 53 rotate synchronously with the sliding of the sliding strip 52, thereby pulling the connecting ring 54. The multiple transmission plates 53 move away from the sliding strip 52. One end of each moving bar 52 is rotatably connected to a connecting ring 54. The function of the connecting ring 54 is to fix the position of the connecting post 56. The connecting post 56 is fixedly connected to the outside of the connecting ring 54. The function of the connecting post 56 is to connect the limiting block 58 and limit the connecting spring 57 at the same time to prevent the connecting spring 57 from shifting. The connecting spring 57 is sleeved on the outside of the connecting post 56. The function of the connecting spring 57 is to compress and rebound outside the connecting post 56 as the connecting post 56 moves. The end of the connecting post 56 away from the connecting ring 54 is fixedly connected to the limiting block 58. The function of the limiting block 58 is to slide in the limiting groove inside the base 1, thereby fixing the position of the support plate 51. Multiple limiting rings 55 are fixedly connected inside the support plate 51. The function of the limiting rings 55 is to restrict the movement of the connecting spring 57. A battery 59 is fixedly connected to the top of the support plate 51. The function of the battery 59 is to supply power to the device. One end of the connecting spring 57 is fixedly connected to the outside of the limiting ring 55, and the other end of the connecting spring 57 is fixedly connected to the rear end of the limiting block 58. The function of fixing both ends of the connecting spring 57 to the outside of the limiting block 58 and the limiting ring 55 is to allow the connecting spring 57 to compress and rebound between the limiting block 58 and the limiting ring 55, thereby limiting the movement of the connecting spring 57. The positioning block 58 can slide inside the limiting groove to achieve a locking effect. The base 1 has multiple limiting grooves inside. The outer side of the limiting block 58 slides inside the limiting groove. The outer side of the connecting column 56 slides inside the limiting ring 55. The outer side of the sliding strip 52 slides inside the dustproof plate 50. The top of the base 1 is fixedly connected to the nozzle 2, which sprays water on the fire. The outer side of the base 1 is fixedly connected to the water inlet 3, which connects to the water supply pipe. The bottom of the base 1 is fixedly connected to the track wheel 4, which enables the equipment to adapt to various terrains.

[0013] Specifically, by pressing the sliding bar 52, the sliding bar 52 can slide, thereby driving the transmission plate 53 to rotate, which in turn causes the transmission plate 53 to pull the connecting ring 54 to move. As the connecting ring 54 moves, it can drive the connecting column 56 to move, thereby causing the limiting block 58 to slide out of the limiting groove. At the same time, the limiting block 58 can press the connecting spring 57, thereby releasing the restriction on the support plate 51, allowing the support plate 51 to drive the battery 59 to slide out of the base 1, thus enabling quick replacement of the battery 59.

[0014] Reference Figure 1 , Figure 4 and Figure 5 The support mechanism 6 includes two protective shells 61. The protective shells 61 protect the air pump 62 and fix its position. The bottoms of the two protective shells 61 are fixedly connected to the front and rear ends of the base 1, respectively. Two air pumps 62 are fixedly connected inside each of the two protective shells 61. The air pumps 62 push the sliding block 63 inside the protective shell 61. The driving end of the air pump 62 is fixedly connected to the sliding block 63. The sliding block 63 allows the support leg 64 to move by the push of the air pump 62. The support leg 64 is fixedly connected to the outside of the sliding block 63. The support leg 64 extends out of the driving end to make the equipment more stable when it is working. The bottom of the base 1 is provided with a clearing component 65. The clearing component 65 clears the space to facilitate the operation of the equipment. The obstacle clearing component 65 includes a fixing block 651, which fixes the position of the obstacle clearing component 65. The top of the fixing block 651 is fixedly connected to the bottom of the base 1. Two dampers 652 are fixedly connected inside the fixing block 651. The dampers 652 absorb the pressure transmitted by the sliding column 654 while connecting to it. A buffer spring 653 is sleeved outside the dampers 652. The buffer spring 653 buffers the pressure transmitted by the sliding column 654 and works simultaneously with the dampers 652 to achieve a buffering effect. The driving end of the dampers 652 is fixedly connected to the sliding column 654. The function of 654 is to fix the position of the fixing plate 655 while sliding inside the fixing block 651. The fixing plate 655 is fixedly connected to the outside of the sliding column 654. The function of the fixing plate 655 is to connect the push plate 656 and the sliding column 654. The push plate 656 is fixedly connected to the outside of the fixing plate 655. The function of the push plate 656 is to clean impurities as it moves. One end of the buffer spring 653 is fixedly connected to the inside of the fixing block 651, and the other end of the buffer spring 653 is fixedly connected to the rear end of the sliding column 654. The outside of the sliding column 654 slides inside the fixing block 651, and the outside of the sliding block 63 slides inside the protective shell 61. Specifically, by moving the equipment, the push plate 656 can clean up debris, and at the same time, it can be buffered by the damper 652 and the buffer spring 653. When working, by starting the air pump 62, the sliding block 63 is pushed to move the support leg 64 to both sides of the equipment. At this time, the support leg 64 is activated, so that the drive end of the support leg 64 extends, thereby making the equipment more stable when working.

[0015] The implementation principle of this application embodiment is as follows: When the device needs to replace the battery 59 for long-term operation after working for a period of time, by pressing the sliding bar 52, the sliding bar 52 can slide inside the support plate 51, thereby driving the transmission plate 53 to rotate with the movement of the sliding bar 52, thereby pulling the connecting ring 54. At this time, with the pulling of the connecting ring 54, the connecting post 56 can slide inside the limiting ring 55, thereby causing the limiting block 58 to move synchronously with the movement of the connecting post 56. At the same time, the movement of the limiting block 58 can press the connecting post 56. The limiting block 58 is retracted, allowing it to slide out of the limiting groove inside the base 1, thereby releasing the restriction on the support plate 51. This allows the support plate 51 to drive the battery 59 to slide out of the base 1. At this time, the fully charged battery 59, along with the support plate 51, slides back into the base 1. When the limiting block 58 contacts the base 1, it retracts inward, thereby compressing the connecting spring 57. After sliding to a certain position, the rebound of the connecting spring 57 allows the limiting block 58 to slide back into the limiting groove, thus fixing the battery 59 and enabling the device to continue working.

[0016] When the equipment moves, it can clear debris from the road surface using the push plate 656. When the push plate 656 pushes large debris, it can push the plate backward, thereby driving the fixed plate 655. This allows the fixed plate 655 to drive the sliding column 654 to slide inside the fixed block 651. As the sliding column 654 slides, it can compress the damper 652 and cause the buffer spring 653 to contract, thus buffering the backward force of the push plate 656. When a clearing is completed and firefighting is needed, the air pump 62 is activated, which pushes the sliding block 63 to slide inside the protective shell 61, allowing the support leg 64 to unfold. At this time, the support leg 64 is activated, allowing the drive end of the support leg 64 to extend, thus preventing the entire equipment from moving due to the recoil force of the water spray during firefighting.

[0017] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
