Description

[0002] The construction machinery operation carbon emission intelligent monitoring device is an intelligent device for real-time monitoring, metering, analyzing and managing carbon emissions generated by construction machinery during operation through Internet of Things, sensors, data analysis and other technologies. For example, the integrated carbon emission monitoring device disclosed in patent publication No. CN117607097A.

[0003] To improve the sensitivity of carbon emission detection, a detection method of laser passing through the exhaust gas of construction machinery is usually adopted. When the laser frequency resonates with the transition energy level of the target gas molecules such as carbon dioxide, the target gas will absorb a certain laser power. By analyzing the laser power change rate, the concentration of greenhouse gases in the gas can be inverted, and the carbon emission of the construction machinery can be calculated. This detection method needs to place two detection elements on both sides of the moving path of the construction machinery. However, when some construction machinery is driving, the tires may burst small stones, and some small stones may hit the surface of the equipment during the splashing process. If it falls on the protective lens of the detection element, it will cause damage to the lens.

When the controller 2 detects that the laser signal is attenuated, it indicates that the dust on the surface of the protective lens 10 is too much, or the protective lens 10 is damaged, which weakens the intensity of the laser. The controller 2 will control the first lead screw linear module 171 and the micro dust suction pump 18 on both sides to work. The first lead screw linear module 171 will drive the dust suction box 172 to move slowly. The rubber scraper 20 on the surface of the dust suction box 172 can scrape off the dust on the surface of the protective lens 10 outside the protective cover 11. At the same time, the micro dust suction pump 18 will suck out the gas in the dust suction box 172, so that the external gas carrying dust enters the dust suction box 172 through the dust suction hole 21 and is stored. The lower end of the dust suction box 172 can be opened for dust cleaning. When the dust suction box 172 moves, the controller 2 will also control the second lead screw linear module 36 and the detection electric push rod 38 to work.

The second lead screw linear module 36 will drive the profile detector 19 to move on the surface of the protective lens 10. The profile detector 19 is used to detect the wear degree of the lens. When the profile detector 19 detects that the protective lens 10 is seriously worn, the protective lens 10 on the surface of the shell 1 needs to be replaced. The controller 2 will control the two second small electric push rods 13 to work. The second small electric push rod 13 will drive the cover 14 to move to the set position away from the shell 1. Then the controller 2 controls the first small electric push rod 71 to work. The first small electric push rod 71 will drive the replacement motor 8, the rotating shaft 9 and the two protective lenses 10 to move to the set position away from the shell 1. Then the controller 2 controls the replacement motor 8 to work. The replacement motor 8 will drive the rotating shaft 9 to rotate. The rotating shaft 9 drives the two protective lenses 10 to rotate one hundred and eighty degrees. The new protective lens 10 prepared before is placed outside the protective cover 11. Then the controller 2 controls the first small electric push rod 71 to drive the protective lens 10 and other components to move close to the protective cover 11, so that the protective lens 10 and the protective cover 11 are in contact, and the optical element 3 is protected; When the shell 1 is in the process of working, the air pump 6 will be in working condition, the air pump 6 will deliver the gas filtered by the filter cover 34 outside to the shell 1, accelerate the flow of air inside the shell 1, discharge the heat inside the shell 1 to the outside, and cool the shell 1, when it rains or the humidity is large outside, the controller 2 will control the four adjusting electric push rods 24 to work, the two adjusting electric push rods 24 on the same side will drive the two blocking boxes 25 to move to the set position in the direction of approaching each other, so that the blocking boxes 25 on the same side contact, block the heat dissipation port 4, avoid the external humidity into the shell 1, at the same time, the controller 2 will also control the air pump 6 to work for a set time, and control the adjusting valve 27 to open, the air pump 6 will deliver the external gas to the buffer cavity 222, and part of the gas will enter the horizontal box 29 through the gas conveying pipe 30, one side of the piston plate 31, the piston plate 31 will drive the electrically conductive frame 32 to move in the horizontal box 29, so that the electrically conductive frame 32 and the resistance plate 33 contact (the end of the resistance plate 33 away from the gas conveying pipe 30 is electrically connected with the controller 2), and then when the external humidity returns to normal, the controller 2 will control the adjusting valve 27 to close, and control the two adjusting electric push rods 24 to work, drive the blocking boxes 25 to restore to the original position by the adjusting electric push rods 24, so that the heat dissipation port 4 is opened, and the buffer cavity 222 is sealed by the blocking boxes 25 (the outer side of the blocking box 25 is provided with a sealing layer, which can ensure the sealing property of the buffer cavity 222), when the stone splashes on the surface of the shell 1 and causes the surface of the shell 1 to be damaged, the gas in the buffer cavity 222 will be gradually discharged through the broken hole, the gas in the horizontal box 29 will be discharged through the broken hole and the gas conveying pipe 30, and under the action of the spring force, the piston plate 31 will drive the electrically conductive frame 32 to slowly move, so that the electrically conductive frame 32 and the resistance plate 33 are in contact at different positions, the resistance in the circuit of the controller 2 changes gradually, in the case that the external voltage is constant, the current intensity delivered to the controller 2 changes, after the controller 2 detects the situation, it indicates that the shell 1 is damaged, the controller 2 will feed back the situation to the receiving end of the monitoring room through the internal wireless communication module, remind the operator to maintain the damaged shell 1 in time, and combine the intelligent oil level meter, the electric carbon meter, the GPS and the intelligent recognition algorithm technology, realize automatic collection of the mechanical running state (construction, movement, shutdown and the like), energy consumption, running track, information of the area where the machine is located and the like, and automatically process and analyze the data through the built-in carbon emission calculation method, calculate the carbon emission generated by the mechanical operation.
