Description

Technical Field

[0001] This utility model relates to the technical field of aerosol detection and sampling equipment, specifically a wheeled miniaturized bioaerosol monitoring and sampling robot. Background Technology

[0002] Bioaerosols refer to aerosols containing biological particles, including bacteria, viruses, allergenic pollen, mold spores, fern spores, and parasite eggs. In addition to the characteristics of general aerosols, they also have infectivity and allergenicity. When sampling bioaerosols, to avoid interference with staff and to prevent operators from affecting the sampling environment, a sampler is used to automatically collect samples, thus conducting sampling in a more stable environment and making bioaerosol sampling more standardized.

[0003] For example, patent CN218239498U discloses a wheeled miniaturized bioaerosol monitoring and sampling robot, including a sampling robot, a mounting plate, and a bioaerosol detection sampler. The mounting plate is fixedly mounted on the top of the sampling robot, and the bioaerosol detection sampler is fixedly mounted on the top of the mounting plate. An auxiliary walking structure is provided on the side wall of the mounting plate, including a first connecting plate and a second connecting plate. A connecting shaft is inserted at the connection between the first and second connecting plates. A fixing plate is fixedly mounted on the end of the first connecting plate away from the second connecting plate, and fixing bolts are provided inside the fixing plate. By designing the auxiliary walking structure and angle adjustment device, normal driving can be achieved on inclined roads or when encountering large obstacles, reducing the occurrence of rollover and improving the protection of the sampler. Therefore, this device is suitable for widespread application.

[0004] Although the auxiliary walking structure can provide additional support on both sides of the robot to prevent it from tipping over, collisions are inevitable during the robot's walking and sampling process. This can cause the sampler above to vibrate violently, or even be damaged upon impact. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a wheeled, miniaturized bioaerosol monitoring and sampling robot. For example, during the robot's walking and sampling process, the front end of the robot is protected to prevent collisions and damage to the robot and the sampler, thereby improving the safety of the robot's movement.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wheeled miniaturized bioaerosol monitoring and sampling robot, comprising a robot body with an aerosol sampler mounted on the top, buffer grooves at both ends of the robot body, buffer mechanisms connected to both buffer grooves, mounting components connected to the side of both buffer mechanisms away from the robot body, and arc-shaped anti-collision plates connected to the side of both mounting components away from the robot body, with the ends of both arc-shaped anti-collision plates extending upwards away from the robot body.

[0007] Furthermore, the buffer mechanism includes a rotating roller and two rotating shafts. Rotating grooves are provided on both sides of the buffer groove, and spring grooves are provided at the ends of the two rotating grooves that are far apart from each other. The two rotating shafts are fixedly connected to both ends of the rotating roller, and the two rotating shafts are rotatably connected to the two rotating grooves. Torsion springs are provided in the two spring grooves. The two torsion springs are respectively sleeved on the two rotating shafts, and one end of the two torsion springs is fixedly connected to the two spring grooves, and the other end is fixedly connected to the two rotating shafts. The mounting assembly is connected to the side of the rotating roller that is far away from the robot body.

[0008] Furthermore, the mounting assembly includes a strip and several mounting bolts. The strip is fixedly connected to the side of the rotating roller away from the robot body. The arc-shaped anti-collision plate has a slot at the end near the robot body. The slot is fitted with the strip and slidably connected to it. The threaded rods of the several mounting bolts pass through the arc-shaped anti-collision plate and the strip and are threadedly connected to nuts.

[0009] Furthermore, both sides of the arc-shaped anti-collision plate are fixedly connected to arc-shaped extension plates, and the overall width of the two arc-shaped extension plates and the arc-shaped anti-collision plate is greater than the width of the robot body.

[0010] Furthermore, the bottom of both ends of the robot body is fixedly connected with a stop bar, which abuts against the bottom of the adjacent insert.

[0011] Furthermore, both the arc-shaped anti-collision plate and the arc-shaped extension plate are hollow structural designs.

[0012] Furthermore, the top height of the arc-shaped anti-collision plate is not lower than the height of the aerosol sampler installed on the top of the robot body.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This wheeled, miniaturized bioaerosol monitoring and sampling robot features arc-shaped anti-collision plates at both ends, protecting it from collisions and preventing damage to the robot and aerosol sampler from other objects during sampling. This ensures more stable sampling operations for the aerosol sampling robot. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1 - Figure 5 A wheeled miniaturized bioaerosol monitoring and sampling robot includes a robot body 1 with an aerosol sampler 11 mounted on the top. Both ends of the robot body 1 are provided with buffer grooves 101. Buffer mechanisms are connected to both buffer grooves 101. Mounting components are connected to the side of both buffer mechanisms away from the robot body 1. Arc-shaped anti-collision plates 2 are connected to the side of both mounting components away from the robot body 1. The ends of both arc-shaped anti-collision plates 2 away from the robot body 1 are curved upwards.

[0023] like Figure 1 - Figure 5 As shown, the wheeled miniaturized bioaerosol monitoring and sampling robot of this utility model is structurally similar to existing wheeled miniaturized bioaerosol monitoring and sampling robots, such as the wheeled miniaturized bioaerosol monitoring and sampling robot disclosed in patent publication number CN218239498U. The main improvement of this utility model lies in the anti-collision protection for the front and rear of the robot during sampling operations to avoid collision damage. Figures 1 to 5As shown, when the wheeled miniaturized bioaerosol monitoring and sampling robot of this utility model is in use, if there is an obstacle in the path of the sampling robot body 1 while it is moving forward to sample, and the robot body does not detect the obstacle and continues to move forward, the arc-shaped anti-collision plate 2 at the front end of the robot body 1 will first come into contact with the obstacle, thereby avoiding damage to the robot body 1 and the aerosol sampler 11 from contact with the obstacle. When the arc-shaped anti-collision plate 2 comes into contact with the obstacle, the forward movement of the robot body 1 is gradually reduced by the buffer mechanism, thereby avoiding the robot body 1 from stopping suddenly and causing damage to the internal electronic components. At the same time, when the robot body 1 moves backward or turns backward, the arc-shaped anti-collision plate 2 at the rear end can protect the rear end of the robot body 1 from collision, further improving the collision protection effect of the robot body 1.

[0024] like Figure 1 - Figure 5 As shown, the buffer mechanism includes a rotating roller 3 and two rotating shafts 4. Rotating grooves 102 are provided on both sides of the buffer groove 101. Spring grooves 103 are provided at the ends of the two rotating grooves 102 that are far apart from each other. The two rotating shafts 4 are fixedly connected to both ends of the rotating roller 3, and the two rotating shafts 4 are rotatably connected to the two rotating grooves 102. Torsion springs 5 ​​are provided in the two spring grooves 103. The two torsion springs 5 ​​are respectively sleeved on the two rotating shafts 4, and one end of the two torsion springs 5 ​​is fixedly connected to the two spring grooves 103, and the other end is fixedly connected to the two rotating shafts 4. The mounting assembly is connected to the side of the rotating roller 3 that is far away from the robot body 1. When the curved anti-collision plate 2 comes into contact with an obstacle, it flips inward in the buffer groove 101 through the rotating roller 3 and two rotating shafts 4. The torsion of the torsion spring 5 prevents the curved anti-collision plate 2 from flipping towards the robot body 1, thereby slowing down the forward speed of the robot body 1. After the collision, it plays a buffering role for the robot body 1. After the robot body 1 moves backward, the torsion spring 5 drives the rotating shaft 4 and rotating roller 3 to rotate outward, thereby flipping the curved anti-collision plate 2 outward and restoring it to its original position.

[0025] like Figure 3 - Figure 5As shown, the mounting assembly includes a strip 6 and several mounting bolts 7. The strip 6 is fixedly connected to the side of the rotating roller 3 away from the robot body 1. The arc-shaped anti-collision plate 2 has a slot 201 at its end near the robot body 1. The slot 201 is fitted with the strip 6 and slidably connected to it. The threaded rods of the mounting bolts 7 pass through the arc-shaped anti-collision plate 2 and the strip 6 and are threadedly connected to nuts 8. When installing the arc-shaped anti-collision plate 2, it is fitted onto the strip 6 fixed to the side of the rotating roller 3 through the slot 201. Then, the mounting bolts 7 are passed through the pre-drilled mounting holes on the arc-shaped anti-collision plate 2 and the strip 6. Finally, the nuts 8 are used to fix the connection between the arc-shaped anti-collision plate 2 and the strip 6. This allows the arc-shaped anti-collision plate 2 to be replaced when it is worn or damaged due to multiple collisions.

[0026] like Figure 1 - Figure 3 As shown, curved extension plates 9 are fixedly connected to both sides of the curved anti-collision plate 2, and the overall width of the two curved extension plates 9 and the curved anti-collision plate 2 is greater than the width of the robot body 1. Two curved extension plates 9 are integrally formed on both sides of the curved anti-collision plate 2, increasing the protectable area at both ends of the curved anti-collision plate 2, thereby completely protecting the entire robot body 1 and the aerosol sampler 11 from the front and back, preventing obstacles from scraping against the sides of the robot body 1 and the aerosol sampler 11, and improving the protective effect.

[0027] like Figure 2 - Figure 5 As shown, both ends of the robot body 1 are fixedly connected to the bottom of a stop bar 10, which abuts against the bottom of the adjacent insert 6. When the torsion spring 5 drives the arc-shaped anti-collision plate 2 to flip outward and reset through the rotating shaft 4 and the rotating roller 3, the stop bar 10 at the bottom of the robot body 1 can prevent the arc-shaped anti-collision plate 2 from flipping outward excessively, thus limiting the initial state of the arc-shaped anti-collision plate 2.

[0028] like Figure 3 As shown, both the arc-shaped anti-collision plate 2 and the arc-shaped extension plate 9 are hollow structures. By making the arc-shaped anti-collision plate 2 and the arc-shaped extension plate 9 hollow, the weight of the front and rear ends of the robot body 1 can be reduced as much as possible, thus preventing the robot body 1 from tipping over.

[0029] like Figure 1 and Figure 2 As shown, the top height of the arc-shaped anti-collision plate 2 is not lower than the height of the aerosol sampler 11 installed on the top of the robot body 1. Designing the top height of the arc-shaped anti-collision plate 2 to be higher than the top height of the robot 1 and the aerosol sampler 11 can better protect the end of the sampling robot and avoid the top of the sampling robot from scraping and colliding with obstacles.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
