Detailed Description

The present invention is further described in detail below with reference to specific embodiments so that those skilled in the art can more clearly understand the present invention.

It should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" are intended to be construed broadly, as if they were connected either fixedly or removably, or as integrally formed structures. To those of ordinary skill in the art, the specific meaning of such terms in this patent may be understood as appropriate.

As shown in fig. 1, the embodiment provides a river sediment real-time sampling device, which includes a high-pressure air source (not shown in the figure), a bracket 1 fixedly installed on a river bank (not shown in the figure), a slide block 2, a sleeve 3, and a sediment extraction pipe 4 slidably sleeved in the sleeve 3;

be equipped with spout 101 on the support 1, spout 101 top end opening extends to 1 upper surface of support, spout 101 bottom opening extends to 1 lower surface of support, 2 slide set up in the

spout

101, 3 tops of sleeve pipe are passed spout 101 bottom opening with 2 bottom surfaces fixed connection of slider, 2 upper ends of slider are equipped with air inlet 100, be equipped with the air flue (not shown in the figure) in the slider 2, the air flue top with air inlet 100 intercommunication, the air flue bottom with 3 intercommunications of sleeve pipe, the high pressurized air source gas outlet with air inlet 100 intercommunication, get husky 4 bottoms of sand pipe and seted up and get husky mouth 401.

Wherein, because the air flue top with air inlet 100 intercommunication, the air flue bottom with sleeve pipe 3 intercommunication makes air inlet 100 with sleeve pipe 3 intercommunication sets up like this, high pressurized air source's gas can pass through air inlet 100 gets into in the air flue, reentrant in the sleeve pipe 3, this moment again because get husky pipe 4 slip cap locate in the sleeve pipe 3, as shown in fig. 4, high pressurized air source's gas can get into in the sleeve pipe 3 to get husky pipe 4 and produce decurrent squeezing action, thereby will get husky pipe 4 and squeeze into the riverbed silt downwards, silt alright in order to pass through get husky mouth 401 entering get husky pipe 4 in, the completion is got husky.

And after the sand is taken out, the air inlet 100 can be communicated with a negative pressure device for vacuumizing, and then the sand taking pipe 4 can be pulled out.

In order to sample the silt of different positions in real time, in this embodiment, slider 2 slide set up in the spout 101, through sliding promptly slider 2 can drive get husky pipe 4 and remove, and then realize carrying out the purpose of sampling in real time to the silt of different positions.

Wherein, the bottom end of the sand taking pipe 4 is hemispherical. The hemispherical shape has strong penetrating power and small damage to the layered structure of the riverbed silt. In some other embodiments, the bottom end of the sand extracting pipe 4 can be funnel-shaped, so that the penetrating power is stronger.

In this embodiment, high-pressure air source includes high-pressure air holding vessel, electric control valve, high-pressure air holding vessel gas outlet with the electric control valve entry intercommunication, the electric control valve export with air inlet 100 intercommunication. The opening and closing of the high-pressure air storage tank can be controlled through the electric control valve, and the high-pressure air storage tank is simple to operate and convenient to use.

As shown in fig. 2, in this embodiment, one end of the bracket 1 is fixedly connected with a fixing surface 5, a fixing hole 6 is formed in the fixing surface 5, and the fixing surface 5 is fixedly mounted on the bank of a river through the fixing hole 6 in cooperation with a rivet.

The fixing surface 5 is provided with four fixing holes 6, and the four fixing holes 6 are distributed at four corners of the fixing surface 5.

In addition, as shown in fig. 2-3, in order to enhance the stability of the slider 2 during sampling, a positioning hole 102 is formed in the bracket 1, a fixing plate 103 is formed in the slider 2, the fixing plate 103 is provided with an insertion hole 104 adapted to the positioning hole 102, and the positioning hole 102 and the insertion hole 104 are fixed by bolts. Through the bolt can with fixed plate 103 with support 1 locking is fixed, and then guarantees the stability when 2 samplings of slider.

The plurality of positioning holes 102 are uniformly arranged on the bracket 1 at intervals along the sliding direction of the sliding groove 101. The arrangement is such that the slide block 2 can be fixed at a plurality of different positions for stable sampling.

In this embodiment, the inner side walls of the two sides of the sliding groove 101 are provided with limiting grooves 105, the side walls of the sliding block 2 are provided with protruding blocks 106 matched with the limiting grooves 105, and the protruding blocks 106 are in sliding fit with the limiting grooves 105. Specifically, the protrusion 106 is embedded in the limiting groove 105, so that the sliding block 2 can stably slide in the sliding groove 101.

As shown in fig. 4, in this embodiment, a sealing portion 7 is fixedly installed at the top end of the sand taking pipe 4, a sealing rubber gasket 8 is fixedly connected to the top end of the sealing portion 7, a side wall of the sealing rubber gasket 8 is tightly attached to an inner side wall of the sleeve 3, and the inner side wall of the sleeve 3 is a smooth surface.
