Description

Technical Field

[0001] The utility model relates to the field of atmospheric environment sampling, in particular to a sampling device for preventing and controlling atmospheric environment pollution. Background Art

[0002] Air pollution is a phenomenon in which certain substances enter the atmosphere due to human activities or natural processes, appear in sufficient concentrations, last for a sufficient period of time, and thus endanger human comfort, health and welfare or the environment. Atmospheric pollutants enter the atmosphere from human or natural sources (input), participate in the atmospheric circulation process, and after a certain residence time, are removed from the atmosphere through chemical reactions, biological activities and physical precipitation in the atmosphere (output). If the output rate is less than the input rate, it will accumulate in the atmosphere, causing the concentration of a certain substance in the atmosphere to increase. When the concentration rises to a certain level, it will directly or indirectly cause acute or chronic harm to humans, organisms or materials, and the atmosphere will be polluted, and it is often necessary to sample and monitor the atmosphere.

[0003] For example, a sampling device for atmospheric pollution prevention and control disclosed in the utility model with authorization announcement number CN216361712U allows the adjustment block to roll inside the slide groove when moving through the auxiliary roller at the bottom, thereby avoiding large friction between the adjustment block and the limit rod, thereby avoiding failures caused by friction and improving the overall service life. When sampling for atmospheric pollution prevention and control, the atmospheric environment of the construction site is sampled through a sampler, but the amount of dust at different heights at the construction site is different, and the device cannot adjust the height of the sampler, so that the sampler cannot sample the atmospheric environment at different heights, resulting in the collected samples being not comprehensive enough. Utility Model Content

[0006] As a preferred technical solution of the utility model, a fixing rod is fixedly connected to the inside of the bottom frame, a screw rod is movably connected between the bottom frame and the fixing rod, a threaded block is sleeved on the outer side of the screw rod and threadedly connected to it, and fixing columns movably connected to the second connecting rod are fixedly connected to both sides of the threaded block, a motor is fixedly connected to one side of the bottom frame, and the rotating end of the motor is fixedly connected to the screw rod.

[0008] As a preferred technical solution of the utility model, an adjusting block is sleeved on the outer side of the limit rod, a fixed disk is fixedly connected to the interior of the adjusting block, a moving column is movably connected to the interior of the fixed disk, a clamping block is fixedly connected to the bottom of the moving column, and a spring is sleeved on the outer side of the moving column and located between the fixed disk and the clamping block.

[0009] As a preferred technical solution of the utility model, a sampler is arranged on the top of the regulating block.

[0010] As a preferred technical solution of the utility model, the shape of the card slot and the card block is trapezoidal, and the sizes are matched.

[0011] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0022] When the height of the sampler 23 needs to be adjusted, the bottom atmospheric environment is first sampled through the sampler 23, and then the motor 13 is driven to rotate the screw rod 10 fixedly connected to its rotating end, and the rotation of the screw rod 10 drives the threaded block 11 threadedly connected to it to move, and the movement of the threaded block 11 drives the fixed column 12 fixedly connected to it to move, and the movement of the fixed column 12 drives the second connecting rod 7 movably connected to it to move, and the movement of the second connecting rod 7 drives the moving block 4, the first connecting rod 6 and the top frame 5 to move, and at this time, the top atmospheric environment is sampled through the sampler 23;

[0023] As a further implementation of this embodiment, Figure 1-Figure 4 As shown, the top of the top frame 5 is fixedly connected with a top plate 14, the top of the top plate 14 is fixedly connected with a fixed block 15, the top of the fixed block 15 is fixedly connected with a limit rod 16, the top of the limit rod 16 is provided with a plurality of slots 17, the outer side of the limit rod 16 is sleeved with an adjustment block 18, the inside of the adjustment block 18 is fixedly connected with a fixed disk 19, the inside of the fixed disk 19 is movably connected with a moving column 20, the bottom of the moving column 20 is fixedly connected with a block 21, the outer side of the moving column 20 is sleeved with a spring 22 located between the fixed disk 19 and the block 21, the top of the adjustment block 18 is provided with a sampler 23, the slots 17 and the block 21 are trapezoidal in shape and matched in size;

[0024] When the position of the sampler 23 needs to be adjusted, the adjustment block 18 is first moved left and right, and the block 21 can be moved out of the slot 17. When the slot 17 is moved out, the moving column 20 is driven to move upward.

Multiple first connecting rods 6 and samplers 23 can be installed to ensure accurate sampling.

[0025] Specific working principle:

[0026] When sampling is needed for atmospheric pollution prevention and control, the device needs to be placed where atmospheric sampling is needed. First, the adjusting block 18 is moved left and right to move the card block 21 out of the card slot 17. When the card slot 17 is moved out, the moving column 20 is driven to move upward, which can cause the spring 22 to contract. When the card block 21 moves to another card slot 17, the force of the spring 22 can move the card block 21 downward to the inside of the card slot 17, so that the card slot 17 and the spring 22 cooperate with each other to fix the adjusting block 18. By installing multiple first connecting rods 6 and samplers 23, the sampling is accurate. When it is necessary to sample the atmospheric environment at different heights, the motor 13 is started to drive the screw rod 10 to rotate, the rotation of the screw rod 10 drives the threaded block 11 to move, the movement of the threaded block 11 drives the fixed column 12 to move, the movement of the fixed column 12 drives the second connecting rod 7 to move, the movement of the second connecting rod 7 drives the top frame 5, the first connecting rod 6 and the moving block 4 to move, and the sampler 23 is driven by the movement of the top frame 5 to adjust its height.
