Description
Technical field
The present invention relates to a kind of pipe testing apparatus, in particular to a kind of magnetic drive pipe detection device.
Background technique
With the development of science and technology, pipeline has been obtained in today's society and is widely applied.Pipeline makes in long-term
It inevitably will appear rupture, blocking etc. in.Pipeline in convey be severe toxicity or radiating medium, if these pipelines generation split
Line, leak hole will cause dielectric leakage, cause accident that disaster even occurs.In order to prevent trouble before it happens, it is necessary to be carried out to these pipelines
Periodic detection and maintenance.Currently, there are many type of detecting robot of pipe, main walking manner has crawler type, wheeled, wriggling
Formula etc., but its structure is all more complicated, and is difficult to minimize.Number of patent application " 201310257284. 8 " proposes one
Kind magnetic drive machine people, but this method cannot be applied on metallic conduit, because the magnet in the structure can adsorb
On pipeline, while metallic conduit has shielding action to magnetic force, cannot drive, and furthermore the patent also could not illustrate external trolley such as
What is attached on pipeline.Based on this, need a kind of structure simple, the pipe detection trolley that can be moved in pipeline very well.
Summary of the invention
It is an object of the invention to propose a kind of magnetic drive pipe detection trolley, keep detection vehicle structure succinct, behaviour
Facilitate.
In order to solve above-mentioned purpose, The technical solution adopted by the invention is as follows:
A kind of magnetic drive pipe detection device, it is characterised in that: described including testing agency and driving mechanism two parts
Testing agency includes detector, permanent magnet and support wheel, and the detector is fixedly linked with permanent magnet, and the permanent magnet can be in pipe
Moved in road, be cylindrical body, two cylinder end faces of the permanent magnet are respectively the pole N and the pole S, the support wheel at least there are three
And be evenly distributed on the cylinder side face of permanent magnet, support wheel guarantee permanent magnet not with tube contacts, support wheel rotating direction and forever
Magnet direction of motion in pipeline is consistent；The driving mechanism includes power supply and the pipe sleeve that is wrapped in outside pipeline, the pipe sleeve by
Semicircle openable and closable upper pipe sleeve and lower pipe sleeve composition, the upper pipe sleeve and down tube put on and are equipped with coil, the upper pipe sleeve and
Down tube covers upper coil and is connected in one and then is connected with power supply, power supply opening, is powered to upper pipe sleeve and down tube set coil, according to
Ampere's law can magnetize metallic conduit, and coil both ends are the pole S, magnetic field strength outside exponentially decline while for the pole N.
Current direction is adjusted, keeps permanent magnet identical with the polarity of pipe sleeve phase proximal end, the principle repelled each other according to same polarity, testing agency will
It is moved forward by pushing, while moving drive mechanism keeps mutual expelling force, so that it may testing agency be allowed constantly to move forward.The present apparatus
A kind of perfect solution is provided for pipeline detection, so that detection device is easy to move and detect in metallic conduit,
Its structure is simple, low in cost, has very big application value.
Preferably, the support wheel has 3-6 group, the multiple groups support wheel is symmetrical with the cylindrical center of permanent magnet,
Described each group has 2-4 support wheel, guarantee permanent magnet not with tube contacts.
Preferably, the detector is camera or supersonic detector.
It is moved in pipeline the medicine have the advantages that driving mechanism slides driving testing agency outside pipeline, the present apparatus
A kind of perfect solution is provided for pipeline detection, so that detection device is easy to move and detect in metallic conduit,
Its structure is simple, low in cost, and different calibers is adapted to by adjusting testing agency's size, can also develop as carrier
Other correlation functions are as cleaned, therefore the present invention has very big application value.
Detailed description of the invention
Fig. 1 is magnetic drive pipe detection device overall construction drawing；
Fig. 2 is driving mechanism schematic diagram.
In Fig. 1: 1- pipeline, 2- detector, 3- permanent magnet, 4- support wheel, the upper pipe sleeve of 5-, pipe sleeve under 6-, 7- power supply.
Specific embodiment
Below with reference to embodiment, the invention will be further described:
As shown in Figure 1, a kind of magnetic drive pipe detection device, including pipeline 1, detector 2, permanent magnet 3, support wheel 4,
Upper pipe sleeve 5, lower pipe sleeve 6 and power supply 7.Wherein detector 2, permanent magnet 3 and support wheel 4 are testing agency；Upper pipe sleeve 5, lower pipe sleeve 6
It is driving mechanism with power supply 7.Testing agency both ends are magnetic, and driving mechanism generates magnetism by electric current, according to magnetic identical phase
Mutually repel or magnetism attracts each other on the contrary, driving mechanism is slided outside pipeline can drive testing agency mobile.
The permanent magnet 3 is cylindrical body, and it is the pole S, 3 cylinder of permanent magnet that one end is the pole N one end to two end faces of cylindrical body respectively
Week, totally 6 support wheels 4, triplets were evenly distributed on around permanent magnet 3 forwards, backwards, and the walking of supports permanent magnets 3 does not connect with pipeline 1
Touching.The upper pipe sleeve 5 and lower pipe sleeve 6 are hollow semi-cylindrical post shapes, equal wound around coil above upper pipe sleeve 5 and lower pipe sleeve 6, upper tube
When set 5 and lower pipe sleeve 6 connect, above corresponding coil also connect forming circuit, lower pipe sleeve 6 is with power supply 7.
The openable and closable upper pipe sleeve 5 and lower pipe sleeve 6 can be bolted into pipe sleeve and cover outside pipeline, tighten bolt
Increase the frictional force of the pipe sleeve and pipeline outer wall fix pipe sleeve relative to pipeline, when needing mobile pipe sleeve, can twist and send spiral shell
Bolt, movement tighten again behind required position, then give coil to be powered again, drive testing agency to advance in pipeline again.
Application method of the present invention are as follows:
Power supply 7 is opened, and upper pipe sleeve 5 and lower 6 coil of pipe sleeve are powered, can be to 1 magnetic of metallic conduit according to Ampere's law
Change, coil both ends are the pole S, magnetic field strength outside exponentially decline while for the pole N.Current direction is adjusted, 3 He of permanent magnet is made
The polarity of pipe sleeve phase proximal end is identical, the principle repelled each other according to same polarity, and testing agency will be moved forward by pushing, mobile simultaneously
Driving mechanism keeps mutual expelling force, so that it may testing agency be allowed constantly to move forward.
It above are only design of the invention to give an example.Invention is not limited thereto, all non-realities carried out to the present invention
The change of matter should all belong to behavior that violates the scope of protection of the present invention.
