As shown in fig. 1 and fig. 2, the present embodiment is an auxiliary detecting device for landfill leachate, which is used for detecting paper carriers 10 with isosceles triangles, and has a supporting plate 8 with an isosceles trapezoid shape, and the left end of the supporting plate 8 is the bottom side of the isosceles trapezoid shape.
In this example, the left end of the supporting plate 8 is connected with the conducting strip 1 for externally connecting a voltage input device, two pressing and holding members are arranged on the supporting plate 8 and close to the left end of the supporting plate 8, the two pressing and holding members are axially and symmetrically arranged on the supporting plate 8 relative to the left and right directions of the supporting plate 8, and the two pressing and holding members are arranged at positions corresponding to two bottom angles of the isosceles triangle paper piece carrier 10 respectively.
The pressing piece in this embodiment has a mount pad 9 fixed on the supporting plate 8, and through the pivot rotatable coupling dwang 3 of parallel supporting plate 8 on the mount pad 9, the pivot is connected to the one end of this dwang, and briquetting 2 is connected to the other end of dwang 3, corresponds briquetting 2 and is equipped with slipmat 4 on supporting plate 8. The pressing block 2 presses the paper sheet carrier 10 under the action of self gravity, and the pressing block 2 inhibits but does not limit the deformation of the paper sheet carrier 10.
In this embodiment, the supporting plate 8 is provided with a transverse buffer mechanism and a transverse pressing mechanism near the right end thereof, wherein the transverse buffer mechanism is located at the left side of the transverse pressing mechanism. The transverse pressing mechanism is provided with a limiting cross rod 12 which is vertical to the axis of the supporting plate 8 in the left-right direction, the limiting cross rod is connected with the supporting plate 8 through a limiting fixing groove 6, and the limiting cross rod 12 is fixed on the limiting fixing groove 6 through a bolt 13; horizontal buffer gear has the buffering horizontal pole 11 of perpendicular layer board 8 left and right sides direction axis arrangement, and this buffering horizontal pole both ends inlay respectively in buffering fixed slot 5, and buffering fixed slot 5 connects on layer board 8.
In this example, the distance between the left end and the right end of the support plate 8 is determined by the fact that the tip of the paper sheet carrier 10 can be exposed out of the right end of the support plate 8 when the bottom corner of the paper sheet carrier 10 is pressed by the pressing member, and the right end of the support plate 8 is connected with a graduated scale 7 for measuring the tip displacement of the paper sheet carrier 10.
In order to avoid the electrical influence on the conductive sheet 1, the relevant parts in this embodiment are made of plastic materials.
