DETAILED DESCRIPTION

[0018] Combined with Figure 1-4As shown, an environmental protection device for collecting landfill gas comprises a landfill pit for degrading garbage and a gas storage mechanism, wherein a first gas channel 1, a second gas channel 2 and a drainage channel 3 are arranged in the landfill pit, a plurality of second gas channels 2 are arranged, the drainage channel 3 is located at the lower end of the landfill pit, a plurality of second gas channels 2 are interconnected with the first gas channel 1, and the other end of the second gas channel 2 is connected with the drainage channel 3, the gas storage mechanism is arranged on the landfill pit and connected with the first gas channel 1, gas enters the gas storage mechanism through the first gas channel 1 and the second gas channel 2 for storage and collection, and the residual water in the landfill pit is discharged through the drainage channel 3;

[0019] Preferably, the air storage mechanism includes a connecting chamber 4, an air pump 5, an air pressure regulating mechanism 6 and an airbag 7. The connecting chamber 4 is connected to the first air channel 1. The air pump 5 and the air pressure regulating mechanism 6 are arranged on the connecting chamber 4. A connecting portion 41 is arranged on one side of the connecting chamber 4. The airbag 7 is fixedly arranged on the connecting portion 41 and is connected to the connecting chamber 4. The air pressure regulating mechanism 6 is transmission-connected to the airbag 7. The air pump 5 pumps the gas in the first air channel 1 into the airbag 7. The air pump 5 can pump out the gas in the landfill pit and input it into the airbag 7. A one-way valve is arranged between the connecting chamber 4 and the first air channel 1 to prevent gas backflow. The air pressure regulating mechanism 6 is used to control the tension and relaxation of the airbag 7 to ensure that the air pressure in the airbag 7 is in a stable state.

[0020] Preferably, two air pressure regulating mechanisms 6 are provided, and an adjusting pressure plate 8 is provided on the side of the airbag 7 away from the connecting chamber 4. The two air pressure regulating mechanisms 6 are respectively installed on both sides of the connecting chamber 4. The air pressure regulating mechanism 6 includes an adjusting motor 61, an adjusting shaft 62 and an adjusting pull wire 63. The adjusting motor 61 is fixedly provided on the connecting chamber 4, and the adjusting shaft 62 is rotatably installed on the connecting chamber 4. The adjusting motor 61 is transmission-connected to the adjusting shaft 62, and the adjusting pull wire 63 is wound on the adjusting shaft 62. One end of the adjusting pull wire 63 is fixedly connected to the adjusting pressure plate 8. The adjusting shaft 62 is driven by the adjusting motor 61 to rotate forward and reversely, so as to control the retraction and release of the adjusting pull wire 63 on the adjusting shaft 62. When the adjusting pull wire 63 is gradually released, the airbag 7 can continue to expand, and the air pressure in the airbag 7 can be reduced. When the adjusting pull wire 63 is gradually tightened, the adjusting pressure plate 8 can be pulled toward the connecting chamber 4. At this time, the airbag 7 gradually shrinks under the pressure of the adjusting pressure plate 8, and the air pressure in the airbag 7 can be increased.

[0021] Preferably, in order to ensure the stable contraction and expansion of the airbag 7, at least one guide rod 42 is provided on the connecting portion 41, and a plurality of guide sleeves are provided on the outer side of the airbag 7, and the plurality of guide sleeves are slidably installed on the guide rod 42. The adjusting pressure plate 8 is slidably installed on the guide rod 42. The stable expansion and contraction of the airbag 7 can be ensured by the mutual cooperation between the guide sleeve and the guide rod 42, and the adjusting pressure plate 8 is further limited. In order to ensure the balance of the equipment during the setting process, four guide sleeves are preferably provided, and the four guide sleeves are used to limit the four sides of the airbag 7, thereby further ensuring the telescopic stability of the airbag 7.

[0022] Preferably, an exhaust port 9 is provided on the connecting cavity 4, and a passage valve 91 is provided at the exhaust port 9. The gas in the airbag 7 can be discharged through the exhaust port 9. When in use, the gas storage device can be installed and connected to the exhaust port 9, and then the passage valve 91 is opened to transport the gas in the airbag 7 to the gas storage device.

[0023] Preferably, in order to facilitate the user to observe the air pressure state in the airbag 7 , a pressure gauge 43 is provided on the connecting cavity 4 .

[0024] Preferably, the first air channel 1 is vertically arranged, and the plurality of second air channels 2 are inclinedly arranged, and the higher side of the second air channel 2 is connected to the first air channel 1, and the lower ends of the plurality of second air channels 2 are connected to the drainage channel 3. The inclined second air channels 2 can guide and collect the gas in the landfill pit, so that the gas is sucked upward by the air pump 5, and the liquid flows downward to the drainage channel 3, thereby realizing the separation of gas and liquid.

[0025] Preferably, in order to further improve the air tightness and stability of the device, a connecting flange is provided on the connecting cavity 4, and the lower end of the connecting cavity 4 is connected to the first airway 1 through the connecting flange.

[0026] When the present application is in use, the odor in the landfill pit is guided through the second channel and the first channel. At this time, the liquid in the landfill pit will flow into the drainage channel 3 through the second channel, and the gas will enter the first channel. The gas collected in the first channel will be sucked into the connecting cavity 4 through the air pump 5 and filled into the air bag 7. The current air pressure value in the air bag 7 can be judged by the pressure gauge. When the air pressure in the air bag 7 is high, the regulating motor 61 is started, and the regulating shaft 62 is driven by the regulating motor 61 to release the regulating pull wire 63, so that the air bag 7 can be further expanded and released, thereby reducing the air pressure value, so that more gas can be stored. When the gas stored in the equipment needs to be discharged, the gas storage device is connected to the exhaust port 9, and the passage valve 91 is opened. The gas in the air bag 7 is discharged through the exhaust port 9. At this time, the regulating shaft 62 can be driven by the regulating motor 61 to tighten the regulating pull wire 63, so that the regulating pressure plate 8 presses the air bag 7, and the gas in the air bag 7 is further pressurized and discharged.
