Description

Technical Field

[0001] The utility model belongs to the technical field of leachate detection equipment, and specifically relates to a leachate detection device for a hazardous waste landfill. Background Art

[0002] The leachate from hazardous waste landfills is a high-concentration organic wastewater, which mainly comes from the water contained in the garbage in the landfill, the rain and snow water entering the landfill, and other water. After deducting the saturated water holding capacity of the garbage and the covering soil layer, it is formed after passing through the garbage layer and the covering soil layer. In addition, it also includes the water that leaks from the accumulated garbage prepared for incineration. The leachate from hazardous waste landfills contains a variety of pollutants, such as ammonia nitrogen, heavy metal ions, highly toxic organic matter, salt and cyanide, etc. Before treating the leachate from hazardous waste landfills, it is necessary to test the harmful components of the leachate, because only by fully understanding the pollution characteristics of the leachate can we select the most appropriate treatment method in a targeted manner, ensure that the leachate is efficiently and safely disposed of, and use the corresponding treatment method to treat the leachate.

[0003] In the existing hazardous waste landfill leachate detection process, since the detection work usually needs to be carried out outdoors, traditional leachate detection equipment faces many inconveniences when carrying. Specifically, whether it is taking the equipment out of the carrying tool or storing the equipment after use, it is quite cumbersome, which undoubtedly greatly reduces the convenience of leachate detection. Utility Model Content

[0004] The purpose of the utility model is to provide a hazardous waste landfill leachate detection device, which can automatically move the detection equipment out of the protection box for use when the cover is opened, and can automatically enter the protection box for storage and protection when the cover is closed, thereby improving practicality.

[0005] The technical solutions adopted in this utility are as follows:

[0006] A hazardous waste landfill leachate detection device comprises a protection box, wherein a first rotating shaft is rotatably installed at a corner of one side of the top of the protection box, two fixed grooves are provided on one side of the protection box, a worm gear is fixed at the bottom end of the first rotating shaft and located in the fixed groove, a mounting groove is provided on one side of the protection box and located between the fixed grooves, a second rotating shaft is rotatably installed on the inner wall of the mounting groove, two ends of the second rotating shaft extend into the fixed groove and a worm engaged with the worm gear is fixed therein, a first bevel gear is fixed on the outer wall of the second rotating shaft and located in the mounting groove, a third rotating shaft is rotatably installed on the inner side of the protection box, one end of the third rotating shaft extends into the mounting groove and a second bevel gear engaged with the first bevel gear is fixed therein, a hydraulic cylinder is fixed at the bottom of the protection box, a movable plate is fixed to the output shaft of the hydraulic cylinder, a tooth plate is provided at the bottom of the movable plate, a third gear engaged with the tooth plate is provided at the other end of the third rotating shaft, a cover plate is fixed to the top of the two first rotating shafts, and a detection device body is provided on the top wall of the movable plate.

[0007] Furthermore, a U-shaped groove is provided on the top of the cover plate, and a handle is rotatably installed inside the U-shaped groove.

[0008] Furthermore, a slide groove is provided on one side of the cover plate, a slider is slidably installed inside the slide groove, a connecting rod is rotatably installed on one side of the slider, and the other end of the connecting rod is rotatably connected to the outer wall of the protection box.

[0009] The technical effects achieved by this utility model are:

[0010] The practical hazardous waste landfill leachate detection device is arranged to move, and when it is moved by the hydraulic cylinder, it will drive the toothed plate to move. During the movement, the toothed plate is in contact and meshing with the gear, driving the second bevel gear on the third shaft to rotate. The second bevel gear drives the worm on the second shaft to rotate by meshing with the first bevel gear. The worm drives the first shaft on the worm wheel to rotate. The first shaft drives the cover plate to rotate and open ninety degrees. The moving plate continues to move upward until the main body of the detection equipment is moved to the top of the protection box. When the cover plate is opened, the detection equipment can be automatically moved out of the protection box for use. When the cover plate is closed, the detection equipment can be automatically placed inside the protection box for storage and protection, thereby improving practicality. The provided handle can facilitate carrying of the equipment, which is more practical. BRIEF DESCRIPTION OF THE DRAWINGS
