It slides column 1, suspension plate 2, place mouth 3, pedestal 4, row's powder structure 5, contact mouth 6, the flat cylinder of the pedestal 4 and intermediate portion
It is provided with an annular contact mouth 6,4 top end face of pedestal is vertically equipped with sliding column 1, the sliding column close to marginal position
1 and pedestal 4 by welder, the 1 vertical direction middle level of sliding column is equipped with suspension plate 2,2 He of suspension plate
Sliding column 1 is glued together, and the end of the suspension plate 2 is provided with a placement mouth 3, and the placement mouth 3 faces contact mouth
6, the row's of being equipped with powder structure 5 inside the pedestal 4, row's powder structure 5 and 3 points sliding 1 bottom center of column, contact of 6 center of circle of mouth
Collinearly, column 1 is slided at 5 both ends of row's powder structure respectively and contact mouth 6 cooperates.
Row's powder structure 5 is mainly by closed plate 51, dust chamber 52, gas channel 53, exhaust structure 54,55 groups of slide post
At the dust chamber 52 is opened in inside pedestal 4, and 52 bottom surface of dust chamber maintains an equal level with 6 bottom surface of contact mouth of pedestal 4, the dust
One is equipped with inside chamber 52 therewith using the closed plate 51 that is slidably matched, the gas channel 53 be L-type structure and its horizontal ends and
Dust chamber 52 is connected to, and 53 vertical end of gas channel is located at sliding 1 vertical direction middle of column, 53 vertical end of gas channel
Horizontal vertical is equipped with exhaust structure 54 at one third from top to bottom, while exhaust structure 54 also is located at suspension plate 2 far from putting
The root of mouth 3 is set, the gentle channel 53 of the exhaust structure 54 is connected to, equivalent equipped with size therewith inside the gas channel 53
Slide post 55, and the two is using being slidably matched.
The exhaust structure 54 mainly includes transfer tube 54a, escape pipe 54b, rotates and fill in 54c, and the transfer tube 54a is gentle
The connection of 53 vertical end of channel, the transfer tube 54a are connected to the one end escape pipe 54b, and the escape pipe 54b is embedded in suspension plate 2,
Matching rotation plug 54c, the rotation plug 54c and outlet are equipped at the port of the escape pipe 54b far from escape pipe 54b
This end pipe 54b uses and is slidably matched.
The closed plate 51 is arc, and interior camber line is equal with contact 6 radian of mouth, when not removing dust, can seal
Close dust and enter dust chamber 52, in the closed plate 51 and slide post 55 between have injection air in the sealing space that constitutes.
Rotation plug 54c is that surface plate 54c-1 and baffle 54c-2 is constituted, the surface plate 54c-1 be ring structure simultaneously
And it is mold integrated formed structure, the gear that its bottom, which is vertically equipped with baffle 54c-2, the baffle 54c-2 and surface plate 54c-1,
Plate 54c-2 and escape pipe 54b is bonded far from the port activity at that end transfer tube 54a, and the area of the baffle 54c-2 is greater than outlet
The cross section of pipe 54b, by whether rotational plane plate 54c-1, to decide whether to open exhaust.
4 bottom of pedestal is equipped with horn-like rubber ring and is not easy mainly for pedestal 4 can be adsorbed on testee
It falls.
In conclusion pedestal 4 is placed on testee or earth's surface, pedestal 4 passes through horn-like rubber ring as far as possible
Ground is adsorbed on its surface, is mounted in the placement mouth 3 of suspension plate 2 after couplant is smeared on probe, gradually pushes, guarantee
Agree with completely with contact mouth 6, will not shift, when probe drops to contact 6 general height of mouth, pulls slide post manually
55, while since the closed plate 51 in dust chamber 52 can be driven to be moved under gas pressure, be located at closed plate 51, pedestal 4,
The space constituted between probe is that the examined object surface powder in the touching mouth 6 in negative pressure space is inhaled into dust chamber 52, is subtracted
Few contact surface dust, at the same pop one's head in also can it is automatic under fall on contact mouth 6 and contact, when slide post 55 slides into 53 vertical end of gas channel
Top can not also allow probe to fall and contact with testee, and there is also portion of air between probe and testee, that is, seal
Closing plate 51 does not move to the most the inside of dust chamber 52, then rotary motion plug 54c, the escape pipe 54b that baffle 54c-2 is blocked connect
It is logical, be then discharged from surface plate 54c-1 gas, slide post 55 and the air of closed plate 51 are discharged during this, oneself however
It so falls after rise, then rotates backward rotation plug 54c, close escape pipe 54b, pull up slide post 55 again and pull closed plate 51, until
The junction that probe whereabouts completely, i.e. closed plate 51 are moved to 52 gas channel 53 of dust chamber, avoids probe contacts face from having powder, empty
Gap is more, so that measurement error is also big.
Problems solved by the invention is that petroleum is located at the deeper position of earth's surface or less, is detected using ultrasonic probe
When, it is used as and measures as medium in the surface coupling agents of probe, and need to completely attach to earth's surface, and gap, powder cannot be generated
Dirt is more, and the error of the bigger measured result of hole is bigger, and the present invention is combined with each other by above-mentioned component, and the present invention passes through
Row's powder structure 5, exhaust structure 54 form negative pressure using sealing, and measurement error is reduced in the gap between absorption probe and contact surface,
It for reinforced suction effect, used can also be vented, slide post 55 is allowed to fall after rise, repeatedly aspirate, not influence last suction effect also
Fruit.
