Hole to the downside of the fixed plate 1, it is preferable that the length that probe 5 stretches out 1 downside of the fixed plate is the length of the tip 52
Degree.Minimum scale wherein on the probe 5 is 1mm.
Preferably, the lower end of the locating rod 3 is fixedly connected with the fixed plate 1, can ensure the company of locating rod 3 in this way
Connect intensity, it is ensured that measuring instrument reliability of operation, it is preferable that the lower end of the locating rod 3 by welding with it is described solid
Fixed board 1 is fixedly connected；Certainly, in this application the locating rod 3 can also be by locating rod 3 by other means with it is described
It is connected through a screw thread, is clamped if the upper end of fixed plate 1 is connected, can equally realize the purpose of the application, objective is not
It is detached from the design philosophy of the utility model, the scope of protection of the utility model should be belonged to.
As depicted in figs. 1 and 2, the sediment thickness measuring instrument further includes hanging ring 21, and the hanging ring 21 is fixed on the peace
The upper end of loading board 2 can be connected by hanging ring 21 with rope is measured in this way when using sediment thickness measuring instrument provided by the present application,
Then more convenient to use by measuring rope extraction or putting down the sediment thickness measuring instrument.
As depicted in figs. 1 and 2, the mounting plate 2 and the fixed plate 1 are circular steel plate, the mounting plate 2 with it is described
The axis collinear of fixed plate 1, and the outer diameter of the fixed plate 1 is more than the outer diameter of the mounting plate 2；Preferably, the mounting plate 2
Thickness be 5mm, outer diameter 50mm, the thickness of the fixed plate 1 is 2mm, outer diameter 100mm.
As shown in Fig. 1,2 and Fig. 5, the locating part 6 includes compressed spring 62, casing 61, fixture block 63 and pull rod 64, described
The side of probe 5 is equipped with continuous card slot 51；Described sleeve pipe 61 is in the tubular structure of one end open, the fixture block 63 and is compressed
Spring 62 is respectively positioned in described sleeve pipe 61, and it is another relative to open end that one end of the compressed spring 62 is resisted against described sleeve pipe 61
On the inner wall at end, the other end is resisted against one end of the fixture block 63, and the other end of the fixture block 63 passes through opening for described sleeve pipe 61
Mouth end extend out to the outside of described sleeve pipe 61, and coordinates with the card slot 51；The card slot 51 includes horizontal 512 He of stop surface
Inclined first inclined-plane 511 (as shown in Figure 4), the lower end on first inclined-plane 511 are connected shape with the inner end of the stop surface 512
At surrounding the card slot 51, and at an acute angle between first inclined-plane 511 and the stop surface 512, the fixture block 63 it is another
End is equipped with the second inclined-plane 631 coordinated with first inclined-plane 511；One end of the pull rod 64 with across described sleeve pipe 61 and with
One end that the fixture block 63 is located in described sleeve pipe 61 is fixedly connected, and the other end of the pull rod 64 is located at outside described sleeve pipe 61
Side.It is in this way that be in compressive state be that the fixture block 63 provides a pretightning force to spring in normal condition, fixture block 63 is caught in described
The first inclined-plane 511 is bonded with the second inclined-plane 631 at this time in a card slot 51 on probe 5, and the lower end of the fixture block 63 is pressed in
On the stop surface 512, by the interference of stop surface 512 and 63 lower end of fixture block, to prevent the probe 5 relative to the fixture block
63 move upwards, and since described sleeve pipe 61 is fixed in fixed plate 1, while fixture block 63 is fixed in described sleeve pipe 61 and is merely able to edge
Horizontal direction moves in described sleeve pipe 61, and the fixture block 63 is perpendicular to the probe 5, therefore the fixture block 63 can prevent
The probe 5 is moved downward relative to the fixed plate 1；Specifically, the direction on first inclined-plane 511 is edge in this application
Direction from the bottom to top by tilting outward from the inside of the locating rod 3, in the same card slot 51, first inclined-plane 511
Lower end be connected with the inner end of the horizontally disposed stop surface 512, the probe 5 described in this way relative to the fixture block 63 downwards transport
When dynamic, fixture block 63 will not be contacted with stop surface 512, do not influenced probe 5 and moved down；When the tip 52 of probe 5 is ejected into hard
When soil layer, the stopping of mounting plate 2 continues to move downward, and probe 5 also stops continuing to move downward, and the lower end of fixture block 63 is stuck in institute at this time
It states on the stop surface 512 of card slot 51, the probe 5 is prevented to move upwards, when lifting measuring instrument at this time, probe 5 is inserted into described heavy
Length in slag 7 will not should be lifting for measuring instrument and change, therefore probe 5 stretches out the length of the bottom fixed board 1 and is
7 thickness of sediment.
The course of work of the utility model is illustrated with reference to Fig. 1 and Fig. 2.
As shown in Figure 1, when the sediment thickness measuring instrument is located at original state, rope will be measured and be bolted on hanging ring 21, then
Lift hanging ring 21, until the upper end of the mounting plate 2 is bonded with the stop nut 4, then proceedes to be lifted up measurement rope, directly
300mm to 500mm is slightly promoted when lifting to entire measuring instrument, measuring instrument is then put into stake holes bottom and bottoming out, it is then loose
Opening measurement rope makes its free-falling, and 7 measuring instrument of this sediment sinks downwards under the effect of gravity at this time, the bottom of 7 measuring instrument of sediment
Fixed plate 1 rest on the top of sediment 7 because the resistance of sediment 7 stops sliding downwards in advance, and probe 5 is made in top disc gravity
It with 5 vertical downward movement of probe and is pierced into sediment 7 with lower continuation, (the second inclined-plane 631 and card slot 51 of fixture block 63 at this time
The fitting of first inclined-plane 511 does not limit the probe 5 and moves downward, i.e. 63 direct motion of fixture block does not work), when the collet of probe 5 touches
And (reverse locking locks probe 5 to fixture block 63 under the pressure of the spring at this time and bottom is solid for stopping whereabouts when the hard soil layer of bottom
The downward relative position of fixed board 1)；
It then will slowly lift measuring instrument to be lifted on ground, and in ground survey or read the stretching bottom fixed board 1 of probe 5
Length be 7 thickness of sediment.
Pull rod 64 is hand-pulled after reading, fixture block 63 retreats at this time, 63 system of bottom fixed board 1 and locating rod 3 and fixture block
Slide downward, the stopping sliding when positioning screw slides into nut location restore initial position, prepare next time system under the effect of gravity
