It aims to improve the traffic capacity, safety and comfort of highways to meet people's travel needs. The main contents of highway engineering include road design, roadbed and pavement construction, bridge and tunnel construction, traffic sign and signal system setting, highway lighting and drainage systems, etc.

[0003] In existing technologies, carbon emissions are constantly increasing. To more effectively regulate and control carbon emissions, carbon sink measurement needs to be performed in different scenarios. However, roads are relatively open, and gas flow is easily affected by vehicles traveling on the road, which can lead to turbulent gas flow. This can cause gas backflow during carbon sink measurement, resulting in errors and affecting the accuracy of carbon sink measurement. Therefore, this utility model designs a carbon sink measurement device for highway engineering. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that the road is relatively open and the gas flow is affected by the driving of cars on the road, which will cause the gas flow direction to be disordered, and may cause gas backflow during carbon sink measurement, resulting in errors in carbon sink measurement and affecting the accuracy of carbon sink measurement. A highway engineering carbon sink metering device is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A carbon sink metering device for highway engineering comprises a box body and an infrared gas analyzer, wherein the infrared gas analyzer is fixedly connected to the inner wall of the box body, and gas collecting hoods are fixedly connected to both ends of the infrared gas analyzer. An air pump is fixedly connected to the side wall of the box body, and the air inlet pipe of the air pump extends to the interior of the box body. A protective cylinder is fixedly connected to the end of the box body facing away from the air pump, and a plurality of air release cylinders are fixedly connected to the side wall of the box body located inside the protective cylinder, and a plurality of air release holes are provided on the cylinder wall of the plurality of air release cylinders.

[0007] Preferably, a spring is fixedly connected to the inner wall of the deflation cylinder, a piston is fixedly connected to one end of the spring relative to the box body, and a side wall of the piston is slidably arranged on the deflation cylinder.

[0008] Preferably, a rubber sealing ring is fixedly connected to the side wall of the piston, and the side wall of the rubber sealing ring is fitted onto the inner wall of the deflation cylinder.

[0009] Preferably, a sealing ring is fixedly connected to the inner wall of the gas collecting hood, and the side wall of the sealing ring is pressed against the side wall of the infrared gas analyzer.

[0010] Preferably, the top of the box body is fixedly connected to a cylinder, the inside of the box body is fixedly connected to a plurality of fixed rods, the rod walls of the plurality of fixed rods are movably provided with guide plates, the insides of the plurality of guide plates are respectively provided with strip openings, the piston rod end of the cylinder is fixedly connected to a connecting rod, and the rod wall of the connecting rod is slidably set on the side wall of the guide plate.

[0011] Preferably, a plurality of shifting rods are fixedly connected to the rod wall of the connecting rod, and the plurality of shifting rods are respectively slidably arranged on the inner wall of the guide plate located at the strip-shaped opening.

[0012] Compared with the existing technology, the present invention provides a highway engineering carbon sink metering device with the following beneficial effects:

[0013] 1. The carbon sink metering device for highway projects uses an air pump to blow gas into the interior of the box. The concentration of carbon dioxide can be measured by an infrared gas analyzer. Subsequently, the gas flows out from the interior of the box through the bleed tube. The gas pushes the piston to drive the spring to compress, so that the gas can flow out through the inner wall of the bleed hole. The rubber sealing ring can improve the sealing performance. At the same time, the air pump stops working and the air pressure is reduced to prevent the gas from flowing back into the bleed tube. The spring will push the piston to block the side wall of the bleed hole to prevent gas from flowing back.

[0014] 2. The highway engineering carbon sink metering device allows the gas to flow evenly to the infrared gas analyzer. The movement of the piston rod of the cylinder drives the connecting rod to move, which can drive the lever to slide along the inner wall of the strip opening, and can push the guide plate to swing along the rod wall of the fixed rod, so as to divert the gas and allow the gas to flow through the infrared gas analyzer more quickly and efficiently.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Example 1

[0021] Reference Figure 1-3 A highway engineering carbon sink metering device includes a box body 1 and an infrared gas analyzer 2. The infrared gas analyzer 2 is fixedly connected to the inner wall of the box body 1. Both ends of the infrared gas analyzer 2 are fixedly connected to a gas collecting cover 3. An air pump 4 is fixedly connected to the side wall of the box body 1. The air inlet pipe of the air pump 4 extends to the interior of the box body 1. A protective cylinder 5 is fixedly connected to the end of the box body 1 away from the air pump 4. A plurality of air release cylinders 6 are fixedly connected to the side wall of the box body 1 located inside the protective cylinder 5. Multiple air leakage holes 11 are opened on the wall of multiple air leakage cylinders 6, and a spring 8 is fixedly connected to the inner wall of the air leakage cylinder 6. The spring 8 is fixedly connected to a piston 9 at one end relative to the box body 1. The side wall of the piston 9 is slidably set on the air leakage cylinder 6, and a rubber sealing ring 10 is fixedly connected to the side wall of the piston 9. The side wall of the rubber sealing ring 10 is fitted on the inner wall of the air leakage cylinder 6. The inner wall of the gas collecting hood 3 is fixedly connected to a sealing ring 7, and the side wall of the sealing ring 7 is pressed tightly on the side wall of the infrared gas analyzer 2.

[0022] During use, the air pump 4 blows gas into the interior of the box 1, and the concentration of carbon dioxide can be measured through the infrared gas analyzer 2. Subsequently, the gas can flow out from the interior of the box 1 through the air release cylinder 6. The gas pushes the piston 9 to drive the spring 8 to compress, so that the gas can flow out through the inner wall of the air release hole 11. The rubber sealing ring 10 can improve the sealing performance. At the same time, the air pump 4 stops working and the air pressure is reduced. In order to prevent the gas from flowing back into the interior of the air release cylinder 6, the spring 8 will push the piston 9 to block the side wall of the air release hole 11 to prevent gas backflow, and the gas collecting hood 3 can make the gas flow more concentratedly through the infrared gas analyzer 3 to prevent gas accumulation inside the box 1.

The rod walls of the plurality of fixed rods 13 are movably sleeved with guide plates 14, and the interiors of the plurality of guide plates 14 are respectively provided with strip openings. The end of the piston rod of the cylinder 12 is fixedly connected to a connecting rod 15, and the rod wall of the connecting rod 15 is slidably set on the side wall of the guide plate 14. A plurality of shift rods 16 are fixedly connected to the rod wall of the connecting rod 15, and the plurality of shift rods 16 are respectively slidably set on the inner wall of the guide plate 14 located at the strip opening.

[0025] In order to make the gas flow evenly to the infrared gas analyzer 2, the piston rod of the cylinder 12 moves to push the connecting rod 15 to move, which can drive the lever 16 to slide along the inner wall of the strip opening and push the guide plate 14 to swing along the rod wall of the fixed rod 13, so as to divert the gas and allow the gas to flow through the infrared gas analyzer 2 more quickly and efficiently.
