Description

Technical Field

[0001] The invention relates to the technical field of fire-fighting robots, in particular to a multifunctional fire-fighting robot. Background Art

[0002] As a kind of special robot, firefighting robot plays a pivotal role in firefighting and emergency rescue. Firefighters can use firefighting robots to suppress dangerous situations in advance, thereby improving the ability to deal with sudden dangerous situations and greatly reducing casualties. At present, the traditional firefighting robots on the market have relatively simple functions. In addition to the functions of water spraying and washing, they have at most a gripper function, which is a single function. Therefore, it is necessary to design a multifunctional firefighting robot that can meet different usage needs in some specific places.

[0003] Existing fire-fighting robots are usually equipped with rotatable monitoring probes to enable the robot to observe the environment inside the fire scene after entering the fire scene by remote control, so as to determine a safe fire-fighting position and locate the fire-fighting point. However, when the fire is large, the fire will be wrapped in thick smoke and cover the field of view of the monitoring probe on the fire-fighting robot, resulting in reduced monitoring visibility, which is not conducive to judging the fire situation, fire intensity and the best fire-fighting position. Existing fire-fighting robots also have a structure that can absorb smoke and dust, but the arrangement position of the smoke and dust absorption structure on the fire-fighting robot is relatively random, and its main function is to absorb smoke and dust, rather than to protect the field of view of the monitoring probe.

DETAILED DESCRIPTION

[0022] The technical scheme of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-Figure 10 As shown, a multifunctional fire-fighting robot comprises a body 1, a walking mechanism 2 is arranged at the bottom of the body 1, a fire-fighting mechanism 3 and a monitoring mechanism 4 are respectively installed on the body 1, a rotatable monitoring camera 41 is arranged on the monitoring mechanism 4, a driving box 5 is also arranged on the body 1, the monitoring mechanism 4 is arranged on the top of the driving box 5, and a rotating air intake frame device 6 which can rotate with the monitoring camera 41 is arranged outside the monitoring mechanism 4. The rotating air intake frame device 6 can firstly realize the synchronous rotation with the monitoring camera 41, and secondly, it can continuously exhaust air in the surroundings of the monitoring direction of the monitoring camera 41 to guide the smoke and dust airflow to be extracted along the edge to avoid it interfering with the monitoring camera 41, and at the same time, avoid the solid particles in the smoke and dust adhering to the monitoring camera 41 and causing pollution to it. At the same time, the rotating air intake frame device 6 can also realize that there is no need to set up an additional stand for fixing itself, thereby avoiding the generation of being near the monitoring camera 41. The rotating air intake frame device 6 is provided with a smoke absorption component 7 distributed around the monitoring camera 41. The rotating air intake frame device 6 is also provided with a cleaning mechanism 8 driven by the smoke absorption component 7 for cleaning the monitoring camera 41. The cleaning mechanism 8 can be controlled by starting and stopping the air source in the smoke absorption component 7, and there is no need to add an additional electric control structure outside the monitoring camera 41, so as to reduce the complexity of the exposed structure and the complexity of the control circuit. Through the cooperation of the rotating air intake frame device 6, the smoke absorption component 7 surrounding the monitoring camera 41 and the driving box 5, it can be achieved that when the monitoring camera 41 rotates, the smoke absorption component 7 can rotate synchronously with the monitoring camera 41, so as to ensure that the smoke near the direction of the monitoring camera 41 is always absorbed during the movement of the monitoring camera 41, so as to protect and expand the field of view of the monitoring camera 41.

[0024] In this embodiment, the monitoring mechanism 4 includes a monitoring support base 42 fixed to the top of the driving box 5 , and a rotation power source for driving the monitoring camera 41 to rotate is arranged in the monitoring support base 42 .

[0025] In this embodiment, the rotating air intake frame device 6 includes a rotating component 61 that can rotate around the outside of the monitoring camera 41. A ring frame component 62 that can fix the annularly distributed smoke absorption component 7 is fixed to the outside of the rotating component 61. The ring frame component 62 can be arranged around the monitoring camera 41 to avoid blocking the monitoring field of view of the monitoring camera 41. An air intake frame component 63 is also arranged behind the ring frame component 62. The air intake frame component 63 can be used to exhaust the smoke absorption component 7. At the same time, it is arranged directly behind the monitoring field of view of the monitoring camera 41 and rotates synchronously with the monitoring camera 41. It can also avoid blocking the field of view of the monitoring camera 41. The air intake frame component 63 is fixed to the monitoring camera 41.

[0026] In this embodiment, the ring frame component 62 includes two mirror-symmetrical half-ring fixing frames 621, and the opposite ends of the half-ring fixing frames 621 are respectively provided with a first connecting portion 6211 and a second connecting portion 6212. The first connecting portion 6211 is used for connecting and fixing the two half-ring fixing frames 621. The half-ring fixing frames 621 are made into two separate parts, which can simplify the mutual assembly operation between them. The second connecting portion 6212 is used to facilitate the connection and fixing of the half-ring fixing frames 621 and the straight edge portion 613 on the movable ring 612. A groove is provided on one side of 212, and the groove is opposite to the straight edge 613 on the movable ring 612 during installation, so that the two can be aligned and installed through fasteners. Two air holes 6213 symmetrically distributed up and down are also provided on the semi-ring fixing frame 621. Both ends of the air hole 6213 are provided with threads. The air hole 6213 is used to allow air to pass through. At the same time, the threads at both ends are convenient for fixing the air inlet pipe 72 and the smoke and dust collecting hood 71, respectively, for easy installation. Two empty slots are also provided on the semi-ring fixing frame 621 to reduce the amount of material used, facilitate molding, and reduce material costs.

[0027] In this embodiment, the smoke absorption component 7 includes a smoke collecting hood 71 threadedly connected to the air hole 6213 near the monitoring direction of the surveillance camera 41. One end of the smoke collecting hood 71 is set to a trumpet shape for increasing the suction range and expanding the absorption range of fire smoke. A filter part 711 for filtering solid pollution particles is arranged in the smoke collecting hood 71. The filter part 711 is evenly distributed with filter holes. The filter part 711 is used to block the solid particles in the absorbed smoke to prevent them from entering the air source component through the pipeline and jamming its structure, causing damage to the air source component. The other end of the air hole 6213 is threadedly connected with an air intake pipe 72. The main body of the air intake pipe 72 is made of flame-retardant material. Sleeves are bonded at both ends of the air intake pipe 72. A threaded metal pipe is rotated in the sleeve to facilitate the connection between the two ends of the air intake pipe 72 and external components. The main body of the air intake pipe 72 can adopt a corrugated pipe to adapt to different installation lengths, and can also be customized and made of hard material to simplify the installation operation.

[0028] In this embodiment, the air intake frame component 63 includes a collar 631 fixedly mounted on the outer lower side of the monitoring camera 41, and a pipe end fixing frame 632 is fixedly mounted between the two semi-ring fixing frames 621. The top view cross-section of the pipe end fixing frame 632 is similar to a crescent shape, and a supporting arc edge is integrally formed near the center of the circle. The supporting arc edge and the inner and outer sides make it convenient to fix the pipe end limiting fixing plate 633. The pipe end fixing frame 632 is fixedly connected to the collar 631, and the pipe end limiting fixing plates 633 are symmetrically arranged on the pipe end fixing frame 632. The adjacent sides of the two pipe end limiting fixing plates 633 are set to an arc shape, and the two arcs constitute a circular cavity with a notch. The circular cavity formed by the The cavity can facilitate the positioning and insertion of the separation delivery pipe 634. At the same time, through the pipe end limit fixing plate 633, the flange portion 6341 on the separation delivery pipe 634 can be conveniently connected and installed with the pipe end limit fixing plate 633 through a locking piece. The separation delivery pipe 634 is inserted into the circular cavity. The outer side of the separation delivery pipe 634 is provided with a flange portion 6341 fixedly connected to the pipe end limit fixing plate 633. The top of the separation delivery pipe 634 is annularly distributed with a plurality of separation end portions 6342. The separation end portions 6342 are used to divide the power of an air source into a plurality of parts, and are respectively connected to the exhaust pipes 635 that need to be exhausted, so as to realize each exhaust pipe 635 The air pressure intensity inside tends to be the same, the number of separation ends 6342 is consistent with the sum of the numbers of air holes 6213 on the two semi-ring fixing frames 621, one end of the air inlet pipe 72 is connected to one of the separation ends 6342, and an exhaust pipe 635 is fixedly connected to the bottom of the separation delivery pipe 634. An exhaust source is provided in the drive box 5, and the air inlet end of the exhaust source is connected to the exhaust pipe 635. The exhaust source can be specifically an air pump. The exhaust pipe 635 should adopt a bellows with a certain flame retardancy. The flame retardancy can be determined by the material of the bellows itself, and can also be formed by coating the outer side of the bellows with a flame retardant material. The length of the bellows should be provided with a section of redundancy. In order to satisfy the freedom of the surveillance camera 41 to rotate within a certain range, and at the same time due to the limitation of the bellows, the corresponding driving structure of the surveillance camera 41 should limit the maximum angle of its left and right rotation, so that no matter how it rotates in either direction, it can only rotate no more than 360 degrees, so as to avoid the bellows from being entangled outside the monitoring support seat 42 to reach the maximum extension limit due to rotation in a single direction. By cooperating with the set ring frame component 62 and the air intake frame component 63, it can be achieved that during the circumferential rotation of the surveillance camera 41, the additional smoke absorption component 7 will not cause any interference with its surrounding field of vision, thereby further protecting the monitoring field of vision of the surveillance camera 41.

[0029] In this embodiment, the cleaning mechanism 8 includes an axis end fixing plate 81 fixedly mounted on the front and rear sides of a half-ring fixing frame 621 on one side. A through hole is opened on the axis end fixing plate 81 to allow the rotation shaft 82 to pass through. At the same time, a sleeve is provided to reduce friction resistance and cooperate with the rotation shaft 82 to reduce the friction force that needs to be overcome for its rotation. A rotation shaft 82 is rotatably connected between the two axis end fixing plates 81. A limiting portion is provided on the outer side of the rotation shaft 82 and on the front side of the front axis end fixing plate 81. At the same time, a protrusion is provided on the surface of the front axis end fixing plate 81. The protrusion cooperates with the limiting portion to position and constrain the rotation shaft 82 at the extreme position under the surveillance camera 41 to ensure that its position is determined after each reset. The front end of 82 is fixed with a rocking bar 83 for cleaning the surveillance camera 41, and a through hole 84 is opened between the air hole 6213 on the side close to the rotating shaft 82 and the rotating shaft 82. The inner diameter of the through hole 84 is smaller than the maximum outer diameter of the ball 86 to prevent the ball 86 from directly entering the adjacent air hole 6213. The through hole 84 is provided with an expansion hole 85 at one end close to the rotating shaft 82, and the ball 86 is arranged in the expansion hole 85. The ball 86 should be made of lightweight material and its own gravity should be reduced as much as possible to reduce its own gravity that needs to be overcome when it is pulled out. A pull wire 87 is glued to one end of the ball 86, and one end of the pull wire 87 is wound around the outside of the rotating shaft 82. The winding direction of the pull wire 87 outside the rotating shaft 82 should meet When the ball 86 pulls the pull wire 87 to move toward the side of the air hole 6213, the pull wire 87 can drive the rocking arm 83 to rotate from the bottom toward the side close to the surveillance camera 41 through the rotating shaft 82. One end of the pull wire 87 is fixedly connected to the outer wall of the rotating shaft 82. The inner thread of the expanded hole 85 is connected with a contact cover 88. The contact cover 88 is used to block the position of the ball 86 in the expanded hole 85 and facilitate the passage of the pull wire 87. A through hole is opened on the abutment cover 88. The outer diameter of the through hole is between the maximum outer diameter of the ball 86 and the outer diameter of the pull wire 87. A torsion spring 89 is also sleeved on the outer side of the rotating shaft 82. The torsion spring 89 is used to quickly reset the ball 86 by pulling the pull wire 87 when it is not affected by the air pressure. , and at the same time drives the rocking arm 83 to reset. The two ends of the torsion spring 89 are respectively fixed to the outer wall of the rotating shaft 82 and the side wall of the adjacent shaft end fixing plate 81. When the vacuum source evacuates the vacuum pipe 635, the airflow transmitted by the separation delivery pipe 634 and the air inlet pipe 72 forms a negative pressure on the side of the ball 86 close to the air hole 6213, so that the ball 86 is quickly pressed to the side close to the air hole 6213 in the expansion hole 85 under the action of the external atmospheric pressure. At the same time, when the ball 86 moves in the expansion hole 85, it synchronously pulls the rotating shaft 82 to rotate through the pull wire 87, so that the rotating shaft 82 drives the rocking arm 83 to rotate, and at the same time, the torsion spring 89 is deformed to store elastic force. When the rocking arm 83 rotates, it passes through the soft cleaning pad 832 thereon.The lens glass of the surveillance camera 41 is contacted and rubbed to wipe it once. After the air exhaust source is turned off, the ball 86 is no longer affected by the external atmospheric pressure. When the rotating shaft 82 is reset under the action of the torsion spring 89, it will drive the rocking arm 83 to swing once, and the lens glass of the surveillance camera 41 is wiped for the second time. Therefore, before and after entering the fire scene, the lens glass of the surveillance camera 41 can be passively wiped twice by actively starting the smoke absorption component. At the same time, during the fire fighting process, if the lens of the surveillance camera 41 is blocked or contaminated, the lens glass of the surveillance camera 41 can be cleaned in the middle of the fire fighting by starting and stopping the air exhaust source. Through the cleaning mechanism 8, when the surveillance camera 41 is adhered to or blocked, the pollutants and obstructions can be pushed away by the rocking arm 83. At the same time, there is no need to set a power source on the periphery of the surveillance camera 41 for this purpose, which reduces the redundancy of the device and avoids the obstruction of the field of view of the surveillance camera 41.

[0030] In this embodiment, a rod body groove 831 for reducing weight is opened on the rocking arm 83, and a soft cleaning pad 832 is detachably connected to the rear side of one end of the rocking arm 83 close to the surveillance camera 41. A Velcro bristle portion is provided at the position for installing the soft cleaning pad 832 on the rocking arm 83 to facilitate the detachable connection between the soft cleaning pad 832 and the rocking arm 83, thereby facilitating the replacement process of the soft cleaning pad 832. The soft cleaning pad 832 can be made of a soft and elastic material to ensure that it can exert a certain squeezing force on the lens glass of the surveillance camera 41 during the swinging of the rocking arm 83, thereby improving the cleaning effect. Secondly, the soft material can reduce the wear caused by friction with the lens glass.

[0031] In this embodiment, the rotating component 61 includes a rib 611 fixed on the outer lower side of the monitoring support seat 42, the rib 611 is used to locate the lowest position of the movable ring 612, and a movable ring 612 is rotatably connected to the outer side of the monitoring support seat 42 and located on the rib 611. The movable ring 612 is used to facilitate the rotation of the ring frame component 62 on the outer side of the monitoring support seat 42, and at the same time, the overall gravity acts on the rib 611 to avoid adding pressure on the monitoring camera 41 to protect the rotating movable structure of the monitoring camera 41. Straight edge portions 613 are integrally formed on two symmetrical sides of the movable ring 612. The straight edge portions 613 can facilitate the connection and fixation between the movable ring 612 and the semi-ring fixing frame 621, and the straight edge portion 613 is detachably connected to the second connecting portion 6212 on the adjacent semi-ring fixing frame 621.

[0032] When the present invention is used in practice, the vehicle body is moved to the fire scene through the walking mechanism 2, and water is supplied to the fire-fighting robot far away from the water source by connecting a long water pipe between the fire-fighting mechanism 3 and the water source in advance. Before the fire-fighting robot is about to enter the fire scene, the exhaust source is started by the remote control, and the air around the outside of the monitoring camera 41 is sucked in through the smoke and dust collecting hood 71 through the coordination among the exhaust pipe 635, the separation delivery pipe 634, the air intake pipe 72, and the air hole 6213, so as to avoid the interference of smoke and dust directly spreading in front of the monitoring camera 41 and its field of vision.
