Distribution, later period testing program easy to adjustment in time, the instrument connection suitable for any depth.
As shown in Figure 1, 2, the top of reference test bar 1 is in cone tip shape, is placed with reading mark 3, reading mark on the top of reference test bar 1
3 width is adapted with the internal diameter of scale drum 4, improves reading efficiency and accuracy.The bottom of reading mark 3 is equipped with notch 5, notch
5, for accommodating the top of reference test bar 1, improve the bonding strength of reading mark 3 with reference test bar 1.It is put down there are two setting the bottom of reading mark 3
Weigh counterweight 7, and counterweight part 7 is evenly arranged in around notch 5, and the cone tip shape top of reference test bar 1 is pressed against using self weight
End, so that it is guaranteed that reading mark 3 can keep horizontality always, to improve the accuracy of reading.
As shown in Figure 1, the water level monitoring device further includes filter cylinder 11 and filter cover 12, filter cover 12 is fixed on filter cylinder 11
Top, the base area of filter cover 12 is greater than or equal to the top surface area of instrument connection, when the later period is by 11 built-in test hole of filter cylinder,
The meeting automatic clamping of filter cover 12 reduces labour outside instrument connection, and is easy to take out filter cylinder 11.Filter cover 12 is equipped with through-hole 15,
Floating ball 2 is located in filter cylinder 11, and the top of reference test bar 1 extends upward outside through-hole 15 and protrudes into scale drum 4, and filter cylinder 11 can prevent
The soil particle of instrument connection side wall is fallen into underground water, guarantees the sensitivity of floating ball 2, it is ensured that accuracy of reading.
As shown in Figure 1, being equipped with guiding device 13 in filter cylinder 11, the outer diameter of guiding device 13 is mutually fitted with the internal diameter of filter cylinder 11
Match, no setting is required, and guiding device 13 can be stuck in filter cylinder 11 by connector, reduce cost.Guiding device 13 is equipped with pilot hole
6, the top of reference test bar 1 passes through pilot hole 6 and protrudes into through-hole 15, and pilot hole 6 is used to limit the transverse shifting of reference test bar 1.Guiding
The aperture in hole 6 is adapted with the outer diameter of reference test bar 1, and pilot hole 6 and through-hole 15 are located on same plumb line, so that reference test bar 1 begins
It is in a vertical state eventually, so that reading mark 3 is in horizontality always, and then improve later period accuracy of reading.
As shown in Figure 1,4 bottom of scale drum is equipped with bracket 8, bracket 8 is used to support scale drum 4.
Wherein, scale drum 4 is made of top of support 9 and hollow out chassis 10, and the top surface of top of support 9 is fixed on the bottom of scale drum 4
Portion, hollow out chassis 10 are fixed on the bottom of top of support 9, and top of support 9 is used to support scale drum 4, and hollow out chassis 10 is used to support
Portion's component.Since several through-holes are distributed in the surface of hollow out chassis 10, take convenient for tester.Top of support 9 is funnel-shaped, engraves
Empty chassis 10 is cyclic annular in open circles, enables reference test bar 1 to pass through bracket 8 and protrudes into scale drum 4.The diameter of hollow out chassis 10 is not
Less than the diameter of through-hole 15 on filter cover 12, directly hollow out chassis 10 can be placed on filter cover 12, reduce labour.
As shown in Figure 1, being stamped part (not shown) of keeping off the rain at the top of scale drum 4, prevent rainwater from entering in instrument connection, influences
The accuracy for the data that later period reads.Top of support 9 is in specifically up-small and down-big funnel-form, can preferably be drained rainwater.
As shown in Figure 1, the bottom of reference test bar 1 be equipped with drainage hole 14, discharge because reference test bar 1 surface fracture due to enter reference test bar
Water in 1 mitigates the weight of reference test bar 1, to improve the sensitivity of floating ball 2.Floating ball 2 is closed housing, i.e. itself and reference test bar 1
It is not communicated with, prevents from influencing the sensitivity of floating ball 2 in the water entered in reference test bar 1 inflow floating ball 2.
The implementation steps of the present embodiment:
1) according to the depth of underground water, the quantity of connecting rod needed for judging, by the end to end composition reference test bar of several connecting rods
1, it is ensured that the top of later period reference test bar 1 can be protruded into scale drum 4, and floating ball 2 is arranged in the bottom end of reference test bar 1；
2) floating ball 2 is placed in instrument connection；Through-hole 15 is inserted in the top of reference test bar 1, filter cylinder 11 and filter cover 12 will be certainly
It is dynamic to fall, until filter cover 12 is fitted on instrument connection；
3) pilot hole 6 is penetrated from the top of reference test bar 1, and guiding device 13 is fixed in filter cylinder 11；
4) reading mark 3 is placed on the top of reference test bar 1；
5) scale drum 4 is connected with bracket 8, and placed it on filter cover 12, while ensured to read mark 3 and being located at scale
In cylinder 4；
6) after reading mark 3 steadily, the burial depth scales and elevation scale in scale drum are read；
7) device is taken out after the completion of test；
8) step 1) -7 is repeated), the recycling of realization device.
The present embodiment is in the specific implementation:
Spreading can be carried out to scale drum 4 according to particular condition in use.
Reference test bar 1 and floating ball 2 use lighter weight, and the production of the light materials such as plastics easy to form improves the spirit of floating ball 2
Sensitivity.Scale drum 4 is made of transparent material, convenient for the state of the real-time observed reading mark 3 of tester.Reading mark 3 and balance
Counterweight 7 because reading mark 3 is located at 1 top of reference test bar, therefore reads 3 matter of mark using the production of the light materials such as the foam of lighter weight
The lighter measure the better, and 7 weight of counterweight part slightly overweights reading mark 3.Bracket 8 is made of light material.Filter cylinder 11 uses
The markets such as light steel wire often make of screen material, can submerged.
Although above embodiments are elaborated referring to conception and embodiment of the attached drawing to the utility model aim,
But those skilled in the art will realize that still may be used in the case where no disengaging claim limits the precondition of range
To make various modifications and variations, such as the shape of scale drum 4 etc. to the utility model, therefore will not repeat them here.
