Problems solved by technology

[0003] Formaldehyde is a poisonous gas, and due to various chemicals in today's society, formaldehyde gas is flooding people's lives. In order to protect people's health, it is usually necessary to detect the concentration of formaldehyde. However, some existing The detection device can only detect the concentration of one point, but cannot detect multiple points in the entire environment, resulting in the final detection effect is not accurate enough, so it needs to be improved

Embodiment 1

[0028] see Figure 1-6 , a mobile collection type formaldehyde gas concentration detection device, comprising a car body 2, the left and right sides of the lower surface of the car body 2 are provided with a first fixed plate 13, the middle part of the first fixed plate 13 is rotatably connected to a first rotating shaft 14, the first The front and rear ends of the rotating shaft 14 are provided with wheels 1, the middle part of the first rotating shaft 14 on the left side is provided with a driven roller 11, the upper surface middle part of the vehicle body 2 is provided with an air storage tank 4, and the upper part of the air storage tank 4 Air inlet 5 is provided. The inside of the air inlet 5 is provided with a one-way valve, and the left end of the car body 2 is provided with a second support column 8, and the middle part of the second support column 8 is slidably connected to the first lifting plate 9, and the lower surface of the first lifting plate 9 A driving roller...

Embodiment 2

[0033] see Figure 5 , the other content of this embodiment is the same as that of Embodiment 1, the difference is that: the front and rear ends of the sliding rod 23 are slidably connected to the second guide rod 24, and the lower end of the second guide rod 24 is rotatably connected to the upper end of the supporting roller, A second spring 25 is arranged between the lower ends of the two guide rods 24 and the sliding rod 23 . In order to ensure that the air outlet 34 can be in close contact with the air inlet 5 of the air tank 4, the second guide rod 24 is set so that when the air outlet 34 contacts the air inlet 5, the second guide rod 24 can move relative to the sliding rod 23 Sliding up and down, the second spring 25 is compressed at this time, so that the second spring 25 provides a clamping force for the contact between the air inlet 5 and the air outlet nozzle 34 .

Abstract

The invention relates to the technical field of gas detection, and discloses a mobile collection type formaldehyde gas concentration detection device which comprises a vehicle body, first fixing plates are arranged on the left side and the right side of the lower surface of the vehicle body, and the middle of each first fixing plate is rotatably connected with a first rotating shaft; wheels are arranged at the front end and the rear end of the first rotating shaft, and a driven roller is arranged in the middle of the first rotating shaft on the left side. An air storage tank is arranged in the middle of the upper surface of the vehicle body, a second supporting column is arranged at the left end of the vehicle body, a first lifting plate is slidably connected to the middle of the second supporting column, a driving roller is arranged in the middle of the lower surface of the first lifting plate, the upper portion of the second supporting column is slidably connected with a second lifting plate, the middle of the second lifting plate is fixedly connected with the left end of a lifting beam, the left and right sides of the lifting beam are slidably connected with the middle of first supporting column. The mobile collection type formaldehyde gas concentration detection device is suitable for pumping gas at different positions into different gas storage tanks, and subsequent detection treatment is facilitated.

Description

technical field [0001] The invention relates to the technical field of gas detection, in particular to a mobile collection type formaldehyde gas concentration detection device. Background technique [0002] Formaldehyde is an organic chemical substance with the formula HCHO or CH 2 O, molecular weight 30.03, also known as formaldehyde. It is a colorless and irritating gas, which is irritating to human eyes and nose. The relative density of gas is 1.067 (air=1), and the density of liquid is 0.815g / cm³ (-20°C). Melting point -92°C, boiling point -19.5°C. Soluble in water and ethanol. The concentration of the aqueous solution can be up to 55%, generally 35%-40%, usually 37%, called formaldehyde water, commonly known as formalin (formalin). [0003] Formaldehyde is a poisonous gas, and due to various chemicals in today's society, formaldehyde gas is flooding people's lives. In order to protect people's health, it is usually necessary to detect the concentration of formaldeh...
