Abstract
Description
Technical Field
[0001] This utility model relates to the field of fire-fighting robot technology, specifically to a lifting platform device for a portable fire-fighting robot. Background Technology
[0002] Firefighting robots are a type of special-purpose robot that are playing an increasingly important role in firefighting and rescue operations. Through advanced technology and powerful functions, they greatly improve the efficiency and safety of firefighting and rescue operations. Firefighting robots can conduct reconnaissance, detection, and search and rescue operations at dangerous disaster sites such as those with toxic substances, oxygen deficiency, or dense smoke.
[0003] Existing firefighting robots use cameras mounted on pan-tilt units to capture images and transmit them in real time for easy reconnaissance and detection of fire environments. However, in actual use, a lifting device is needed to obtain a wide field of view. Furthermore, the presence of particulate matter such as smoke in fire environments can adhere to the lens, affecting the clarity of the detection. Therefore, further improvements are needed. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides the following technical solution: a lifting platform device for a portable fire-fighting robot, comprising a robot body, a rotating seat on the top of the robot body, a lifting assembly for lifting on the top of the rotating seat, a mounting base fixedly mounted on the top of the lifting assembly, a camera mounted on the top of the mounting base, a movable groove at the front end of the mounting base, and a mirror cleaning assembly for cleaning the front mirror of the camera on the bottom side of the front end of the mounting base.
[0005] As an optimization, the lifting assembly includes a fixed cylinder fixedly installed at the center of the top side of the rotating seat. A lifting cylinder is slidably inserted inside the fixed cylinder. A screw is screwed inside the lifting cylinder. The screw is driven to rotate inside the lifting cylinder by a transmission motor inside the rotating seat. The transmission motor drives the screw to rotate inside the lifting cylinder, which in turn drives the lifting cylinder to rise and fall along the inner wall of the fixed cylinder.
[0006] As an optimization, limit strips are fixedly installed on both sides of the lifting cylinder, and limit grooves are opened on the inner wall of the fixed cylinder corresponding to the limit strips. The limit strips are slidably inserted into the limit grooves. By sliding the limit strips in the limit grooves, the rotation of the lifting cylinder can be restricted.
[0007] As an optimization, four guide cylinders are fixedly installed on the top side of the rotating seat and on the outer side of the lifting cylinder. Guide rods are slidably inserted inside the guide cylinders, and buffer springs are sleeved on the outer sides of the guide cylinders and guide rods. The lifting and lowering of the mounting seat will drive the guide rods to slide inside the guide cylinders, thereby playing a guiding role and stretching and compressing the guide rods to play a certain buffering role.
[0008] As an optimization, the mirror cleaning assembly includes a support fixedly installed on the bottom side of the mounting base. A guide rail is fixedly installed on the bottom of the support, and a rack plate is slidably connected inside the guide rail. A transmission component is also provided on the bottom side of the mounting base for driving the rack plate to slide back and forth. A cleaning component that swings back and forth to clean the camera mirror is rotatably connected inside the support. The transmission component drives the rack plate to slide back and forth along the inner wall of the guide rail, which in turn drives the cleaning component to swing back and forth, thereby cleaning the camera mirror.
[0009] As an optimization, the transmission component includes a servo motor fixedly mounted on the bottom side of the mounting base, a crank fixedly mounted on one end of the output shaft of the servo motor, a rotating column rotatably connected to the end of the crank, a ring frame fixedly mounted in the middle of the rack plate, and the rotating column rotatably connected inside the ring frame.
[0010] As an optimization, the cleaning component includes a rotating shaft rotatably connected inside the support. A gear is fixedly installed at one end of the rotating shaft near the U-shaped frame, and the gear meshes with a rack plate. A rotating plate is fixedly installed at the other end of the rotating shaft. The rotating plate is slidably inserted into the interior of the movable groove. A cleaning brush is glued to the side of the rotating plate opposite the camera, and the cleaning brush abuts against the mirror surface of the camera.
[0011] The beneficial effects of this utility model are:
[0012] The lifting platform of this portable firefighting robot uses a crank to rotate a column that presses against the inner wall of a retaining frame. This causes the retaining frame to slide back and forth with the crank, which in turn causes the rack plate to slide back and forth along the guide rail. This, in turn, causes the gears to rotate back and forth, which in turn causes the rotating plate to swing back and forth via a rotating shaft. This, in turn, causes the cleaning brush to wipe and clean the lens of the camera, preventing the detection clarity from being reduced due to the adhesion of particulate matter such as smoke.
[0013] The lifting platform of this portable firefighting robot rotates inside the lifting cylinder via a screw, causing the lifting cylinder to rise and fall along the inner wall of the fixed cylinder. This, in turn, drives the camera on top of the mounting base to rise and fall synchronously. The detection height can then be adjusted as needed, thus facilitating the acquisition of a wide field of view for reconnaissance and detection of the fire environment. Attached Figure Description

[0019] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0020] 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.
[0021] Please see Figure 1 A lifting platform device for a portable fire-fighting robot includes a robot body 1, a rotating seat 2 on the top of the robot body 1, a lifting assembly 3 for lifting on the top of the rotating seat 2, a mounting base 4 fixedly installed on the top of the lifting assembly 3, a camera 5 installed on the top of the mounting base 4, an active groove 6 at the front end of the mounting base 4, and a mirror cleaning assembly 7 for cleaning the front mirror of the camera 5 on the bottom side of the front end of the mounting base 4.
[0022] Please see Figure 2The lifting assembly 3 includes a fixed cylinder 8 fixedly installed at the center of the top side of the rotating seat 2. A lifting cylinder 9 is slidably inserted inside the fixed cylinder 8. A screw 10 is screwed inside the lifting cylinder 9. The screw 10 is driven to rotate inside the lifting cylinder 9 by the transmission motor inside the rotating seat 2. The transmission motor drives the screw 10 to rotate inside the lifting cylinder 9, which in turn drives the lifting cylinder 9 to rise and fall along the inner wall of the fixed cylinder 8. Therefore, the camera 5 on the top of the mounting base 4 will rise and fall synchronously, which is convenient for obtaining a wide field of view to detect and investigate the fire environment.
[0023] Please see Figure 2 Limiting strips are fixedly installed on both sides of the lifting cylinder 9. Limiting grooves are opened on the inner wall of the fixed cylinder 8 corresponding to the limiting strips, and the limiting strips are slidably inserted into the limiting grooves. By sliding the limiting strips in the limiting grooves, the rotation of the lifting cylinder 9 can be restricted, thereby facilitating the vertical lifting of the lifting cylinder 9. Four guide cylinders 11 are fixedly installed in an array on the top side of the rotating seat 2 and on the outer side of the lifting cylinder 9. Guide rods 12 are slidably inserted into the inside of the guide cylinders 11, and buffer springs 13 are sleeved on the outside of the guide cylinders 11 and the guide rods 12. When the mounting seat 4 is raised or lowered, the guide rods 12 will slide inside the guide cylinders 11, thereby playing a guiding role and stretching and compressing the guide rods 12, playing a certain buffering role.
[0024] Please see Figure 3-4 The mirror cleaning assembly 7 includes a support 14 fixedly installed on the bottom side of the mounting base 4. A guide rail 15 is fixedly installed on the bottom of the support 14. A rack plate 16 is slidably connected inside the guide rail 15. A transmission component is also provided on the bottom side of the mounting base 4 to drive the rack plate 16 to slide back and forth. A cleaning component that swings back and forth to clean the mirror surface of the camera 5 is rotatably connected inside the support 14. The transmission component will drive the rack plate 16 to slide back and forth along the inner wall of the guide rail 15, which will in turn drive the cleaning component to swing back and forth, thereby cleaning the mirror surface of the camera 5.
[0025] Please see Figure 3-4 The transmission components include a servo motor 17 fixedly mounted on the bottom side of the mounting base 4. A crank 18 is fixedly mounted on one end of the output shaft of the servo motor 17. A rotating column 19 is rotatably connected to the end of the crank 18. A ring frame 20 is fixedly mounted in the middle of the rack plate 16, and the rotating column 19 is rotatably connected inside the ring frame 20. When the servo motor 17 is started, the crank 18 will rotate, which will in turn cause the rotating column 19 to press against the inner wall of the ring frame 20, so that the ring frame 20 slides back and forth with the crank 18, thereby causing the rack plate 16 to slide back and forth along the inside of the guide rail 15 for transmission.
[0026] Please see Figure 3-4The cleaning component includes a rotating shaft 21 rotatably connected inside the support 14. A gear 22 is fixedly installed at one end of the rotating shaft 21 near the U-shaped frame 20, and the gear 22 meshes with the rack plate 16. A rotating plate 23 is fixedly installed at the other end of the rotating shaft 21. The rotating plate 23 is slidably inserted into the interior of the movable groove 6. A cleaning brush 24 is glued to the side of the rotating plate 23 opposite to the camera 5, and the cleaning brush 24 abuts against the mirror surface of the camera 5. The gear 22 can be driven to rotate back and forth by sliding the rack plate 16, which in turn will drive the rotating plate 23 to swing back and forth through the rotating shaft 21, thereby driving the cleaning brush 24 to wipe and clean the mirror surface of the camera 5.
[0027] When in use, first control the robot to drive into the designated area, then start the drive motor, which will drive the screw 10 to rotate inside the lifting cylinder 9, so that the lifting cylinder 9 will rise and fall along the inner wall of the fixed cylinder 8, which will drive the camera 5 on the top of the mounting base 4 to rise and fall synchronously. At this time, the detection height can be adjusted as needed, so as to obtain a wide field of view for reconnaissance and detection of the fire environment.
[0028] At the same time, starting the servo motor 17 will drive the crank 18 to rotate, which will in turn drive the rotating column 19 to press against the inner wall of the return frame 20, causing the return frame 20 to slide back and forth with the crank 18. This will cause the rack plate 16 to slide back and forth along the inside of the guide rail 15, which will drive the gear 22 to rotate back and forth. This will then drive the rotating plate 23 to swing back and forth through the rotating shaft 21, which will drive the cleaning brush 24 to wipe and clean the lens of the camera 5.
[0029] In summary, the lifting platform device of this portable fire-fighting robot, when the crank 18 is rotated, will cause the rotating column 19 to press against the inner wall of the retaining frame 20, so that the retaining frame 20 slides back and forth with the crank 18. This will cause the rack plate 16 to slide back and forth along the inside of the guide rail 15, which will drive the gear 22 to rotate back and forth. In turn, the rotating shaft 21 will drive the rotating plate 23 to swing back and forth, which will drive the cleaning brush 24 to wipe and clean the lens of the camera 5 back and forth, so as to avoid the reduction of detection clarity due to the adhesion of particulate matter such as smoke.
[0030] The screw 10 rotates inside the lifting cylinder 9, causing the lifting cylinder 9 to rise and fall along the inner wall of the fixed cylinder 8. This, in turn, drives the camera 5 on the top of the mounting base 4 to rise and fall synchronously. At this time, the detection height can be adjusted as needed, thereby facilitating the acquisition of a wide field of view for reconnaissance and detection of the fire environment.
