Description

Technical Field

[0001] The utility model relates to the technical field of garbage landfill, in particular to a garbage landfill gas collection shaft pipeline structure. Background Art

[0002] When domestic waste is landfilled, it will produce landfill gas with methane and carbon dioxide as the main components.

[0003] As long as the landfill site meets certain conditions, landfill gas can be effectively utilized. There are many common ways to reuse landfill gas, but no matter which way is used, the landfill gas must first be extracted from the landfill layer through the extraction well. The extraction well can be divided into two types: vertical well and horizontal well, each of which has its appropriate time to use.

[0004] The prior art publication number CN215844810U is a liquid and gas collection shaft structure suitable for large-scale landfills, including a shaft body, a guide bottom cover, a filter element placement groove, a soft filter element strip, a liquid storage tank, an air guide pipe, and a liquid guide pipe. First, the shaft body and the guide bottom cover are buried deep inside the landfill, and the surrounding area is landfill garbage. When the garbage decomposes, leachate and odorous gas will enter the shaft body.

[0005] Although the shaft pipeline can discharge leachate and gas, in actual use, it cannot detect the amount of leachate inside the liquid storage tank. Therefore, it cannot automatically extract according to the amount of leachate inside the liquid storage tank. It is necessary to manually control the self-priming pump to extract the leachate. During the extraction process, it is also necessary to observe the leachate extraction situation from time to time to avoid the self-priming pump idling for a long time and prevent pump damage. The main reason is that the leachate inside the liquid storage tank is non-quantitative and the extraction completion time cannot be estimated, which is time-consuming and labor-intensive. For this reason, improvements are proposed. Utility Model Content

[0006] The utility model is a landfill gas collection shaft pipeline structure proposed to solve the shortcomings in the prior art.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a landfill gas collection shaft pipeline structure, comprising a shaft body, a drainage pipe is fixedly mounted on the top of the shaft body, one end of the drainage pipe is fixedly penetrated by a pump body, and an outlet pipe is fixedly penetrated by the output end of the pump body;

[0008] The top of the shaft body is fixedly connected with a horizontal plate, the top of the horizontal plate is fixedly connected with a shell, the top of the shell is penetrated by a knob, and the knob and the shell are threadedly connected, and the bottom of the knob is fixedly installed with a pressure sensor;

[0009] The detection end of the pressure sensor is abutted against an elastic component;

[0010] The housing is equipped with a detection component, and the detection component matches the elastic component;

[0011] A floating plate assembly is installed between the shell and the transverse plate, and the floating plate assembly is connected to the elastic force assembly.

[0012] Furthermore, the elastic component includes an upper slide plate, and the upper slide plate abuts against the detection end of the pressure sensor. Two springs are symmetrically fixedly connected to the bottom of the upper slide plate, and the bottoms of the two springs are commonly fixedly connected to a lower slide plate. After the lower slide plate is subjected to pressure, the pressure sensor can detect the pressure value through the spring and the upper slide plate.

[0013] Furthermore, the upper slide plate and the lower slide plate are slidably connected with two slide bars, and the slide bars are fixedly connected to the shell. The slide bars have a limiting effect on the upper slide plate and the lower slide plate, and can ensure the stability of the movement of the upper slide plate and the lower slide plate.

[0014] Furthermore, the float plate assembly includes a float plate body, and the float plate body is arranged on the inner side of the vertical shaft body. A movable rod is fixedly connected to the top of the float plate body, and the movable rod passes through the horizontal plate and slides sealed therewith. The movable rod is fixedly connected to the lower slide plate. When the liquid level reaches the set height, the float plate body can be pushed to move.

[0015] Furthermore, the detection component includes an alarm and a travel switch, and the alarm is fixedly mounted on the top of the shell, and the travel switch is fixedly mounted on an inner wall of one side of the shell. The travel switch matches the lower slide plate, and the travel switch and the alarm are electrically connected. When the travel switch is pressed, the alarm will be activated.

[0016] Furthermore, the bottom opening of the drainage pipe is close to the inner bottom of the shaft body, so that each time the leachate is extracted, the liquid in the shaft body can be extracted to the greatest extent.

[0017] Furthermore, an exhaust pipe is arranged on the top of the shaft body, which is beneficial to the discharge of gas in the shaft body.

[0018] Beneficial effects of the utility model:

[0019] When the utility model is in use, the landfill gas collection shaft pipeline structure can monitor the amount of leachate in the shaft body through the set drainage pipe, pump body, liquid outlet pipe, cross plate, shell, knob, pressure sensor, elastic component, detection component and floating plate component. When the set amount is reached, the leachate can be automatically pumped out without manual operation, which saves time and effort and can also avoid idling of the pump body. At the same time, when the pressure sensor fails and causes insensitive sensing, the detection component can promptly remind the staff to handle it. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] like Figures 1 to 3As shown, it relates to a landfill gas collection shaft pipeline structure, including a shaft body 1, a drainage pipe 4 is fixedly mounted on the top of the shaft body 1, one end of the drainage pipe 4 is fixedly penetrated by a pump body 3, an output end of the pump body 3 is fixedly penetrated by a liquid outlet pipe 5, the bottom opening of the drainage pipe 4 is close to the inner bottom of the shaft body 1, and the pump body 3 can extract the leachate in the shaft body 1 through the drainage pipe 4 and the liquid outlet pipe 5.

[0028] A horizontal plate 16 is fixedly connected to the top of the shaft body 1, and a shell 10 is fixedly connected to the top of the horizontal plate 16. A knob 12 is provided through the top of the shell 10, and the knob 12 is threadedly connected to the shell 10. A pressure sensor 13 is fixedly installed at the bottom of the knob 12. The pressure sensor 13 is a limit technology, and its model can be selected according to actual needs. The setting of the knob 12 is conducive to the replacement operation of the pressure sensor 13.

[0029] The detection end of the pressure sensor 13 is abutted against an elastic component, which includes an upper slide plate 14, and the upper slide plate 14 is abutted against the detection end of the pressure sensor 13. Two springs 15 are symmetrically fixedly connected to the bottom of the upper slide plate 14, and the bottoms of the two springs 15 are commonly fixedly connected to the lower slide plate 11. Two sliding rods 8 are commonly slidably connected between the upper slide plate 14 and the lower slide plate 11, and the sliding rods 8 are fixedly connected to the shell 10. The sliding rods 8 can ensure the stability of the movement of the upper slide plate 14 and the lower slide plate 11.

[0030] The shell 10 is equipped with a detection component, and the detection component is matched with the elastic component. The detection component includes an alarm 7 and a travel switch 9. The alarm 7 is fixedly mounted on the top of the shell 10, and the travel switch 9 is fixedly mounted on an inner wall on one side of the shell 10. The travel switch 9 is matched with the lower slide plate 11. The travel switch 9 is a non-self-locking touch switch, which is started after being pressed and automatically resets after contact and pressing, which is conducive to the start and stop of the alarm 7.

[0031] A floating plate assembly is installed between the shell 10 and the cross plate 16, and the floating plate assembly is connected to the elastic assembly.
