To the upper end of outer tube 4, to realize the measurement to liquid level.
The upper end of the inner sleeve 5 is additionally provided with limit along platform 18, and the inner sleeve 5 is wholely set with limit along platform 18,
By, along platform 18, preventing inner sleeve 5 in rotation, the distance mistake that inner sleeve 5 moves down in the setting limit of the upper end of inner sleeve 5
It is more；Meanwhile it is convenient when needing to rotate inner sleeve 5, people can quickly hold 5 upper end of inner sleeve and rotate, and make
The rotation of inner sleeve 5 is more convenient.
It is marked with graduation mark on second electric connection line 7, the second electric connection line 7 is enable quickly to read when moving down
The length that second electric connection line 7 moves down out, to quickly obtain the distance between liquid level and ground.The inner sleeve 5
It arranges with 4 spaced radial of outer tube, keeps movement of the inner sleeve 5 in outer tube 4 more smooth.
It is multiple in the fixation hole 3, it is inserted with testing agency in multiple fixation holes 3, enables multiple testing agencies simultaneously
Liquid level is measured, keeps the data measured more accurate.The earth anchor 2 at least two, and multiple earth anchors 2 are along mounting plate
Central symmetry arrangement, and the support force for being subject to mounting plate is more balanced, finally makes the installation of mounting plate more firm.
When needing to measure the liquid level in well, first earth anchor 2 is plugged and is fixed on the ground, and by reversed beam 1
It is concordant with ground, then reversed beam 1 is fixed, measuring mechanism is passed through into fixation hole 3 at this time and is inserted into well.If desired to well
When interior liquid level measures, inner sleeve 5 is rotated, by the cooperation of internal screw thread 17 and external screw thread 16, makes inner sleeve 5 in rotation
It moves gradually downward, with continuing to rotate for inner sleeve 5, makes the lower end of inner sleeve 5 when continuing to move down, inner sleeve 5
Lower end pushes the rotation of arc valve, and the lower end of outer tube 4 is made to be opened, and enters 4 lower end of outer tube by inlet opening 11 at this time
Liquid level enters the upper end of outer tube 4, and enters in inner sleeve 5；When mud enters in inner sleeve 5, mud and second
The circuit trigger 8 of 7 lower end of electric connection line contacts, at this time the first electric connection line 6, inner sleeve 5, mud, circuit trigger 8, the
Two electric connection lines 7, voltmeter 9 are formed into a loop, and start turning the pointer of voltmeter 9, to measure the height of the liquid level in well
Degree.
In measurement process, if the circuit trigger 8 for being fixed on 7 upper end of the second electric connection line makes back not in contact with to mud
Road trigger 8 not can be carried out work, and the second electric connection line 7 is disconnected with inner sleeve 5 at this time, make the first electric connection line 6 and the second electricity
Connecting line 7 is not connected to, and 9 pointer of voltmeter is slack, thus to detect liquid level.
When measuring mechanism, which is inserted into, not to be needed to measure liquid level in well, the lower end of inner sleeve 5 is far from arc
Valve pushes against the abutting spring 13 being fixed on 4 inner wall of outer tube by arc valve, to make multiple arcs valve be closed, thus will
The lower end of outer tube 4 is closed, and prevents the mud for entering 4 lower end of outer tube from continuing into 4 upper end of outer tube.
The present invention can effectively detect the liquid level in well, and measurement is accurate, structure is simple, at low cost, easy to use, and
It can be used for carrying out liquid level monitoring or other need the field of seal shaft.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
