Abstract
Description
Technical Field
[0001] This utility model belongs to the field of environmental monitoring technology, specifically referring to a gas quantitative detection environmental monitoring device. Background Technology
[0002] Gas detection refers to the detection and analysis of gaseous components in air, water, or other media using specific sensors, and gas detection equipment is often used.
[0003] Gas detection equipment typically uses a fan or air pump to draw air into the detection chamber, where a detector with a probe detects the gas, and then returns and records the data.
[0004] However, using fans or air pumps in the gas detection process often makes it difficult to control the amount of air drawn in, resulting in poor subsequent detection results. In addition, large-molecule harmful particles may be drawn in at the same time as the gas, which will contaminate the detection probe inside the equipment and reduce its service life. Therefore, there is an urgent need for a quantitative gas detection environmental monitoring device to solve the above problems. Utility Model Content

A gas extraction pipe with its end extending into the housing is fixedly connected to one side wall of the housing. A gas extraction assembly is provided on the other side wall of the housing. A detection assembly located on one side of the gas extraction pipe is also provided inside the housing.
[0007] The air extraction assembly includes a cylinder fixed to the other side wall of the housing, and a piston slidably disposed on the inner wall of the air extraction pipe. The output end of the cylinder is connected to a connecting rod, and one end of the connecting rod extends into the air extraction pipe and is connected to the piston.
[0008] The detection assembly includes a detection box fixed to the inner wall of the housing, and a detector located on one side of the detection box on the outer wall of the end of the housing, with a connecting pipe connecting the detection box and the detector.
[0009] Furthermore, the air extraction assembly also includes a rubber strip disposed at the other end of the air extraction pipe, a limiting block for blocking the rubber strip is fixed on the inner wall of the other end of the air extraction pipe, and an L-shaped limiting member for preventing the rubber strip from rebounding is fixed at the other end of the air extraction pipe.
[0010] Furthermore, the width of the limiting block is half that of the rubber strip.

[0013] Furthermore, an exhaust valve is fixedly installed on the other side wall of the testing box.
[0014] The beneficial effects of this utility model by adopting the above structure are as follows:
[0015] 1. Equipped with an air extraction component, the piston is pushed by the cylinder and connecting rod to move back and forth in the exhaust pipe, continuously drawing in air or expelling it through the exhaust pipe.

[0024] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0025] Example 1:
[0026] refer to Figure 1 As shown, in order to achieve the above functions, the technical solution adopted by this utility model is as follows: a gas quantitative detection environmental detection device includes a housing 1 and a support leg 2 set at the lower end of the housing 1. A suction pipe 3 with its end extending into the housing 1 is fixedly connected to one side wall of the housing 1. A suction assembly is provided on the other side wall of the housing 1. A detection assembly located on one side of the suction pipe 3 is also provided inside the housing 1.
[0027] like Figure 1-4 As shown, the vacuum assembly includes a cylinder 6 fixed to the other side wall of the housing 1, and a piston 12 slidably disposed on the inner wall of the vacuum pipe 3. A connecting rod 11 is connected to the output end of the cylinder 6, and one end of the connecting rod 11 extends into the vacuum pipe 3 and connects to the piston 12. The vacuum assembly also includes a rubber strip 4 disposed at the other end of the vacuum pipe 3. A limiting block 13 for blocking the rubber strip 4 is fixed to the inner wall of the other end of the vacuum pipe 3. The width of the limiting block 13 is half that of the rubber strip 4, and it only blocks half of the rubber strip 4. The other end of the suction pipe 3 is fixed with an L-shaped limiting piece 5 to prevent the rubber strip 4 from rebounding, thus blocking the other half of the rubber strip 4 in the opposite direction. When the cylinder 6 pulls back the connecting rod 11, the piston 12 moves to one end and sucks half of the rubber strip 4 into the suction pipe 3, exposing a gap. Gas is sucked into the suction pipe 3, and then the cylinder 6 pushes the gas in the suction pipe 3. The rubber strip 4 is reset under the push of the gas and is blocked by the L-shaped limiting piece 5 at the end of the suction pipe 3, and the gap disappears.
[0028] The detection assembly includes a detection box 8 fixed to the inner wall of the housing 1, and a detector 7 located on one side of the detection box 8 on the outer wall of the end of the housing 1. A connecting pipe 10 is connected between the detection box 8 and the housing 3. The cylinder 6 pushes the gas into the connecting pipe 10 through the connecting rod 11 and the piston 12, and then enters the detection box 8 for detection.
[0029] Example 2:
[0030] Based on Example 1, such as Figure 1-5 As shown, an exhaust pipe 9 is fixedly installed on the side wall of the suction pipe 3, and a piston 14 is slidably installed on the inner wall of the exhaust pipe 9. A spring 15 is provided between the piston 14 and the inner wall of the exhaust pipe 9 to connect the two. An exhaust hole is opened on the outer wall of the exhaust pipe 9. When the piston 12 passes through the connection point between the connecting pipe 10 and the suction pipe 3, a new cavity is formed. The gas in the cavity is compressed and pushes the piston 14 until the exhaust hole is exposed. The gas is discharged from the exhaust hole. After the gas is discharged, the spring 15 resets the piston 14 and the exhaust hole is closed.
[0031] The detection assembly also includes a probe 17 fixedly connected to the detector 7 and extending into the cavity of the detection chamber 8. A filter housing 16 is inserted into the lower end of the connecting tube 10. Multiple round holes are evenly provided on the outer wall of the insertion end of the filter housing 16 to filter in large molecular harmful particles. An exhaust valve is fixedly provided on the other side wall of the detection chamber 8 to discharge the exhaust gas from the inside of the detection chamber 8 after the detection is completed.
