Embodiment 1

[0049] A pipeline outer wall electric spark detection device, such as figure 1 and figure 2 As shown, it includes a main body mechanism 1, a walking mechanism 2, and an electric spark leak detection module 3. The main body mechanism 1 includes a first torus 11, a second torus 12 and a connecting rod 13 connecting them. The first torus 11 includes a first ring 111 and a second ring 112 from left to right, and the side of the second ring 112 is fixedly connected to the connecting rod 13;

[0050] Such as Figure 4As shown, the traveling mechanism 2 includes a first driving wheel 21 and a first driven wheel 22, the first driving wheel 21 is driven by a first motor 23, and the first motor 23 is installed on the connecting rod 13 near the first ring body 11 side , the first driven wheel 22 is rotatably mounted on the side of the connecting rod 13 away from the first ring body 11;

[0051] Such as Figure 5 and Figure 6 As shown, the EDM leak detection module 3 includes an ED...

Embodiment 2

[0074] The difference from Example 1 is that the outer wall of the connecting rod 13 is sprayed with an anti-corrosion layer, and the anti-corrosion layer is prepared by the following method:

[0075] Take the following raw materials and weigh them by weight: Take the following raw materials and weigh them by weight: 6 parts of polyacrylic acid emulsion, 3 parts of polystyrene acrylic emulsion, 3 parts of organic bentonite paste, 4 parts of quartz powder, 9 parts of modified phenolic resin, 12 parts of polyvinyl acetate, 8 parts of polyisocyanate, 9 parts of binder, 4 parts of defoamer, 20 parts of mineral base oil;

[0076] A: Material preparation: first weigh the above raw materials;

[0077] B: Grease-ester mixing: first add the mineral base oil to the constant temperature magnetic stirrer, then pour the modified phenolic resin, polyvinyl acetate and polyisocyanate into the constant temperature magnetic stirrer, turn on the constant temperature magnetic stirrer to stir and ...

Embodiment 3

[0084] The difference with embodiment 2 is the preparation of anti-corrosion layer, and its specific preparation method is as follows:

[0085] Take the following raw materials and weigh them by weight: take the following raw materials and weigh them by weight: 8 parts of polyacrylic acid emulsion, 7 parts of polystyrene acrylic acid emulsion, 5 parts of organic bentonite paste, 8 parts of quartz powder, 13 parts of modified phenolic resin, 16 parts of polyvinyl acetate, 12 parts of polyisocyanate, 13 parts of binder, 8 parts of defoamer, 30 parts of mineral base oil;

[0086] A: Material preparation: first weigh the above raw materials;

[0087] B: Grease-ester mixing: first add the mineral base oil to the constant temperature magnetic stirrer, then pour the modified phenolic resin, polyvinyl acetate and polyisocyanate into the constant temperature magnetic stirrer, turn on the constant temperature magnetic stirrer to stir and heat, the speed At 50r / min, the temperature is c...

Abstract

The invention discloses an electric spark detection device for the outer wall of a pipeline, comprising a main body mechanism, a walking mechanism and an electric spark leakage detection module. The main body mechanism comprises a first torus, a second torus and a connecting rod connecting the first torus and the second torus; the walking mechanism comprises a first driving wheel and a first driven wheel, the first driving wheel is driven by a first motor; the electric spark leakage detection module comprises an electric spark detector and a mobile device, a second driving wheel and a second driven wheel are rotatably arranged on the supporting rod from top to bottom sequentially, the second driving wheel is driven by a second motor, the electric spark detector comprises an electric sparkbrush. According to the electric spark detection device for the outer wall of the pipeline, omnibearing detection of round pipelines is facilitated, the whole device operates steadily, detection efficiency and detection precision are greatly improved, and pressure between the electric spark brush and the outer wall of a metal pipe can be conveniently adjusted, so that cost is saved.

Description

technical field [0001] The invention belongs to the technical field of electric spark detection, and in particular relates to a pipe outer wall electric spark detection device. Background technique [0002] The electric spark detector can detect the coating. If there are pinholes or other leaks on the coating, the brush on the detector can make electronic contact with the metal below the leak, thereby generating electric sparks. The inspectors The missing coating point can be judged according to the electric spark. [0003] At present, the leak detectors on the market are basically hand-held, with low detection efficiency and poor detection quality, and cannot perform good detection on the outer wall of the pipeline. Contents of the invention [0004] The object of the present invention is to provide a pipeline outer wall electric spark detection device, to solve the above-mentioned background technology, the leak detectors on the market are basically hand-held, the detec...
