Description

Technical Field

[0001] This application relates to the field of sampling equipment technology, and in particular to a portable indoor sampling device. Background Technology

[0002] Indoor environmental testing is a scientific activity that uses modern scientific and technological methods to quantitatively measure the concentration changes of environmental factors and other indoor environmental pollutants that are harmful to human health in an intermittent or continuous manner, and to observe and analyze the process and extent of their environmental impact.

[0003] Currently, traditional sampling equipment needs to be moved to different locations when collecting air or surface samples. During this process, the sampling equipment may collide with obstacles. Traditional sampling equipment cannot protect the base when it collides with obstacles, making the base prone to damage. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a portable indoor sampling device for detection, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0005] To achieve the above objectives, this application adopts the following technical solution: a portable indoor sampling device, including a base, a moving mechanism inside the base, four support mechanisms symmetrically distributed on the surface of the base, a protective mechanism on one side of the base, the protective mechanism including a telescopic rod fixedly connected to the base, a protective plate fixedly connected to the side of the telescopic rod away from the base, a spring sleeved on the outside of the telescopic rod, a sleeve rod rotatably connected to the top of the base, a rotating mechanism on one side of the sleeve rod, a height adjustment mechanism inside the sleeve rod, and a sampler body fixedly connected to the top of the height adjustment mechanism.

[0006] In a preferred embodiment, the moving mechanism includes an electric push rod, which is fixedly connected to the base. A moving plate is fixedly connected to the bottom of the electric push rod, and the moving plate is slidably connected to the base. Four moving wheels are installed on the bottom of the moving plate, and the four moving wheels are symmetrically distributed on the bottom of the moving wheels.

[0007] By adopting the above technical solution, the telescopic end of the electric push rod extends and retracts to move the moving plate inside the base, and then the moving wheels at the bottom of the moving plate touch the ground and roll along the designated route to move the base, which can make the base move more effectively.

[0008] In a preferred embodiment, the support mechanism includes a fixed block, which is fixedly connected to the base. A rotating rod is threadedly connected to the inside of the fixed block. A turntable is fixedly connected to the top of the rotating rod, and a support block is rotatably connected to the bottom of the rotating rod.

[0009] By adopting the above technical solution, the rotating rod is limited by the fixed block, and then the rotating turntable makes the rotating rod rotate. The rotation of the rotating rod causes the support block at the bottom of the rotating rod to touch the ground, thus supporting the base. This provides better support for the base.

[0010] In a preferred embodiment, the rotating mechanism includes a second motor, which is fixedly connected to the base. A drive gear is fixedly connected to the output end of the second motor, and a driven gear meshes with one side of the drive gear. The driven gear is fixedly connected to the sleeve rod.

[0011] By adopting the above technical solution, the output end of motor two rotates to drive the drive gear to rotate, which in turn drives the driven gear to rotate, which in turn drives the sleeve rod to rotate, and the sleeve rod to rotate the sampler body. This allows the sampler body to rotate more effectively.

[0012] In a preferred embodiment, the height adjustment mechanism includes a motor, which is fixedly connected to a sleeve rod. A threaded rod is fixedly connected to the output end of the motor, and a movable rod is threadedly connected to the external side of the threaded rod. The movable rod is slidably connected to the sleeve rod, and two limiting rods are fixedly connected to the external side of the movable rod. The two limiting rods are symmetrically distributed on the surface of the movable rod, and the limiting rods are slidably connected to the sleeve rod.

[0013] By adopting the above technical solution, the output end of motor one rotates to drive the threaded rod to rotate, and the rotation of the threaded rod drives the moving rod to move inside the sleeve rod. The limiting rod limits the moving rod to prevent the moving rod from rotating with the threaded rod. The movement of the moving rod then drives the sampler body to move, which can better enable the sampler body to move.

[0014] In a preferred embodiment, the sleeve rod has a sliding groove inside, which is adapted to the limiting rod.

[0015] By adopting the above technical solution, a sliding groove is provided inside the sleeve rod, which is adapted to the limiting rod, and the limiting rod is limited by the sliding groove, so that the limiting rod can be better limited.

[0016] In a preferred embodiment, a rubber protective pad is fixedly connected to the surface of the protective plate.

[0017] By adopting the above technical solution, a rubber protective pad is fixedly connected to the surface of the protective plate, and the rubber protective pad protects the protective plate, which can better protect the protective plate.

[0018] In a preferred embodiment, a wireless communication device and a power supply are fixedly connected to the surface of the base, and both the wireless communication device and the power supply are electrically connected to the sampler body.

[0019] By adopting the above technical solution, both the wireless communication device and the power supply are electrically connected to the sampler body. The power supply provides power to the sampler body, and the wireless communication device transmits the data collected by the sampler body to a mobile APP or other remote terminal for display. This allows for better transmission of the collected data to the mobile APP or other remote terminal for display.

[0020] The beneficial effects of this application are:

[0021] 1. This portable indoor sampling device, by setting up a protective plate, a telescopic rod and a spring, uses the telescopic rod to support and limit the protective plate, the protective plate to block obstacles, and the spring to buffer the impact force on the protective plate and reset the protective plate. This avoids the problem of traditional sampling equipment being unable to protect the base when it hits an obstacle, which leads to the base being easily damaged, thus improving its practicality.

[0022] 2. This portable indoor sampling device comprises a motor, a limiting rod, a threaded rod, and a moving rod. The output of the motor rotates, causing the threaded rod to rotate. The rotation of the threaded rod then causes the moving rod to move inside the sleeve. The limiting rod limits the movement of the moving rod to prevent it from rotating with the threaded rod. The movement of the moving rod then moves the sampler body, increasing the detection range of the sampler body. This avoids the problem of traditional sampling equipment being unable to move the sampler body, thus improving its practicality. Attached Figure Description

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0029] Reference Figures 1-2 A portable indoor sampling device includes a base 1. The base 1 has a moving mechanism 4 inside, which includes an electric push rod 41 fixedly connected to the base 1. A moving plate 42 is fixedly connected to the bottom of the electric push rod 41 and slidably connected to the base 1. Four moving wheels 43 are symmetrically distributed at the bottom of the moving plate 42. The moving plate 42 moves inside the base 1 by extending and retracting the telescopic end of the electric push rod 41. The moving wheels 43 at the bottom of the moving plate 42 then contact the ground and roll along a designated path, moving the base 1 more effectively.

[0030] Reference Figures 1-2 The base 1 has four support mechanisms 3 symmetrically distributed on its surface. Each support mechanism 3 includes a fixing block 33, which is fixedly connected to the base 1. A rotating rod 32 is threadedly connected to the inside of the fixing block 33. A turntable 31 is fixedly connected to the top of the rotating rod 32, and a support block 34 is rotatably connected to the bottom of the rotating rod 32. The fixing block 33 limits the rotation of the rotating rod 32, and the turntable 31 rotates the rotating rod 32. The rotation of the rotating rod 32 causes the support block 34 at the bottom of the rotating rod 32 to contact the ground, thus supporting the base 1. This provides better support for the base 1.

[0031] Reference Figures 1-4A protective mechanism 2 is provided on one side of the base 1. The protective mechanism 2 includes a telescopic rod 22, which is fixedly connected to the base 1. A protective plate 21 is fixedly connected to the side of the telescopic rod 22 away from the base 1. A spring 23 is sleeved on the outside of the telescopic rod 22. A sleeve rod 7 is rotatably connected to the top of the base 1. A rotating mechanism 6 is provided on one side of the sleeve rod 7. A height adjustment mechanism 5 is provided inside the sleeve rod 7. The sampler body 8 is fixedly connected to the top of the height adjustment mechanism 5.

[0032] Reference Figures 1-3 The rotating mechanism 6 includes a second motor 61, which is fixedly connected to the base 1. A drive gear 62 is fixedly connected to the output end of the second motor 61. A driven gear 63 meshes with one side of the drive gear 62, and the driven gear 63 is fixedly connected to the sleeve rod 7. The rotation of the output end of the second motor 61 drives the drive gear 62 to rotate, which in turn drives the driven gear 63 to rotate, which in turn drives the sleeve rod 7 to rotate, and finally the sleeve rod 7 to rotate the sampler body 8. This allows the sampler body 8 to rotate more effectively.

[0033] Reference Figure 3 The height adjustment mechanism 5 includes a motor 51, which is fixedly connected to the sleeve rod 7. A threaded rod 53 is fixedly connected to the output end of the motor 51. A moving rod 54 is threadedly connected to the outside of the threaded rod 53. The moving rod 54 is slidably connected to the sleeve rod 7. Two limiting rods 52 are fixedly connected to the outside of the moving rod 54. The two limiting rods 52 are symmetrically distributed on the surface of the moving rod 54 and are slidably connected to the sleeve rod 7. The rotation of the output end of the motor 51 drives the threaded rod 53 to rotate, and the rotation of the threaded rod 53 drives the moving rod 54 to move inside the sleeve rod 7. The limiting rods 52 limit the moving rod 54 to prevent it from rotating with the threaded rod 53. The movement of the moving rod 54 drives the sampler body 8 to move, which can better enable the sampler body 8 to move.

[0034] Reference Figure 3 The sleeve rod 7 has a sliding groove inside, which is adapted to the limiting rod 52. By having a sliding groove inside the sleeve rod 7, which is adapted to the limiting rod 52, and then limiting the limiting rod 52 by the sliding groove, the limiting rod 52 can be better limited.

[0035] Reference Figure 4 A rubber protective pad is fixedly connected to the surface of the protective plate 21. The rubber protective pad is fixedly connected to the surface of the protective plate 21, and the protective plate 21 is protected by the rubber protective pad, which can better protect the protective plate 21.

[0036] Reference Figures 1-3The surface of the base 1 is fixedly connected to a wireless communication device 9 and a power supply 10. Both the wireless communication device 9 and the power supply 10 are electrically connected to the sampler body 8. Since both the wireless communication device 9 and the power supply 10 are electrically connected to the sampler body 8, the power supply 10 provides power to the sampler body 8, and the wireless communication device 9 transmits the data collected by the sampler body 8 to a mobile APP or other remote terminal for display. This allows for better transmission of the collected data to the mobile APP or other remote terminal for display.

[0037] Working principle: The telescopic end of the electric push rod 41 extends and retracts, causing the moving plate 42 to move inside the base 1. Then, the moving wheels 43 at the bottom of the moving plate 42 contact the ground and roll along a designated route, moving the base 1. The fixed block 33 limits the rotation rod 32. The rotating turntable 31 causes the rotating rod 32 to rotate. The rotation of the rotating rod 32 causes the support block 34 at the bottom of the rotating rod 32 to contact the ground, supporting the base 1. The output end of the second motor 61 rotates, driving the drive gear 62 to rotate. The drive gear 62 rotates, driving the driven gear 63 to rotate. The driven gear 63 rotates, driving the sleeve rod 7 to rotate. The sleeve rod 7 rotates, driving the sampler body 8 to rotate. The first motor 5... The output end of 1 rotates, driving the threaded rod 53 to rotate. The rotation of the threaded rod 53 then drives the moving rod 54 to move inside the sleeve rod 7. The limiting rod 52 limits the moving rod 54 to prevent it from rotating with the threaded rod 53. The movement of the moving rod 54 then drives the sampler body 8 to move. The power supply 10 provides power to the sampler body 8. The wireless communication device 9 transmits the data collected by the sampler body 8 to a mobile APP or other remote terminal for display. When the base 1 hits an obstacle, the telescopic rod 22 supports and limits the protective plate 21. The protective plate 21 then blocks the obstacle. The spring 23 buffers the impact force on the protective plate 21 and resets the protective plate 21.
