Detailed Description

The present application is described in further detail below with reference to figures 1-2.

The embodiment of the application discloses a simple deep well exploration water taking device, which comprises a sampling barrel 1 and a suspension rope 11, wherein the sampling barrel is arranged in the sampling barrel 1; an iron ring is embedded in the center of one end face of the sampling barrel 1, a suspension rope 11 is tied on the iron ring to be fixed with the sampling barrel 1 and used for retracting and releasing the sampling barrel 1 in the well, and the sampling barrel 1 extends into the well and collects a water sample at the bottom of the well.

As shown in fig. 1 and 2, the whole appearance of sampling bucket 1 is cylindricly, and sampling bucket 1 has the protruding 2 of receiving water towards the one end shaping in shaft bottom, receives the protruding inside of protruding direction orientation sampling bucket 1 of water 2, then sampling bucket 1 has the groove structure that corresponds with the protruding 2 of receiving water towards the outer terminal surface shaping in shaft bottom. Receive protruding 2 of water and be coniform, and receive the axis coincidence of protruding 2 of water and the axis of sampling bucket 1, have seted up the hole 21 of fetching water on the conical surface of receiving protruding 2 of water, in this embodiment, the quantity of the hole 21 of fetching water is four, and four holes 21 of fetching water use the axis of receiving protruding 2 of water to arrange as central annular array. The exhaust hole 12 is seted up to the one end that sampling bucket 1 is connected with suspension rope 11, and when the one end submergence below the surface of water of sampling bucket 1 orientation shaft bottom, under hydraulic effect, water in the well gushes into sampling bucket 1 through the hole 21 of fetching water in, and at this in-process, exhaust hole 12 plays the effect of maintaining sampling bucket 1 internal pressure stable to make the water sample can get into in sampling bucket 1 smoothly.

As shown in fig. 1 and 2, the conical surface of the water collecting protrusion 2 in the sampling barrel 1 is hinged with a water inlet plate 22, the hinged point of the water inlet plate 22 and the water collecting protrusion 2 is located on one side of the water taking hole 21 away from the bottom of the well, and the rotating plane of the water inlet plate 22 relative to the water collecting protrusion 2 is parallel to the axis of the water collecting protrusion 2. The surface of the water inlet plate 22 is a cambered surface, and under the action of no external force, the self-weight action of the water inlet plate 22 enables the surface of the water inlet plate 22 facing the water taking hole 21 to be abutted with the conical surface of the water collecting protrusion 2 in an attaching mode, so that the water taking hole 21 can be plugged by the water inlet plate 22. When sampling barrel 1 submerges below the liquid level of well water towards the one end in shaft bottom, the water pressure that sampling barrel 1 tip department formed acts on the face of the one side of board 22 orientation water intaking hole 21 that intakes, and board 22 is washed away by rivers to intake, and water intaking hole 21 is switched on, and well water alright get into in the sampling barrel 1.

As shown in fig. 1 and 2, according to keeping away from of linker can know, the inside water level of sample bucket 1 is the same with the outer well water level of sample bucket 1, and when pulling out sample bucket 1 to the well head, the water in the sample bucket 1 can be kept away from the face in water intake hole 21 one side to water intake plate 22 under the action of gravity and form the impact, thereby make water intake plate 22 reverse upset in order to seal water intake hole 21, the water in the sample bucket 1 just is loaded and is taken out by sample bucket 1. Receive protruding 2 of water and be located welded fastening on the conical surface of sampling bucket 1 inside and have limit stop 23, limit stop 23 is located one side that the hole 21 of fetching water was kept away from to the pin joint of board 22 of intaking and receiving protruding 2 of water, and limit stop 23 carries out the stroke spacing to the biggest reversible angle of board 22 of intaking: the focus of water inlet plate 22 need be located its pin joint all the time and keep away from the axis one side of receiving water protruding 2, make water inlet plate 22 can reset smoothly when aiming at putting out sampling bucket 1 in the well. In this embodiment, the limiting stopper 23 limits the water inlet plate 22 to allow the water inlet plate 22 to turn over by 60 ° at most.

As shown in fig. 1 and 2, because the water receiving protrusion 2 is in a conical shape, inside the sampling barrel 1, an annular groove-shaped structure is formed between the water receiving protrusion 2 and the inner side wall of the bottom of the sampling barrel 1, and the bottom of the annular groove is lower than the water taking hole 21, and due to the existence of the water level difference at the bottom of the sampling barrel 1, the process that well water enters the sampling barrel 1 through the water taking hole 21 is accompanied with the surging of water flow. Intercepting plates 24 are integrally and fixedly connected between the water collecting bulge 2 and the inner wall of the sampling barrel 1, the number of the intercepting plates 24 is four, all the intercepting plates 24 are arranged in a row by taking the axis of the water collecting bulge 2 as a central ring, the plate surface of each intercepting plate 24 is parallel to the axis of the sampling barrel 1, and the edge of each intercepting plate 24, which is far away from the bottom end of the sampling barrel 1, is higher than the water taking hole 21; the existence of the interception plate 24 ensures that an annular groove formed between the water collecting bulge 2 and the inner wall of the sampling barrel 1 is not unobstructed any more, and after water flow enters the bottom of the sampling barrel 1, the kinetic energy of the water sample is quickly weakened under the interception action of the interception plate 24, so that the turbulent flow degree of the water flow entering the sampling barrel 1 is reduced; to the solid particle impurity that gets into in the sampling bucket 1 along with the water sample, the kinetic energy of rivers reduces and also can make solid particle impurity subside fast, reduces the mutual mixing effect of impurity to sample quality of water.

As shown in figures 1 and 2, the end part of the sampling barrel 1 facing the bottom of the well is fixedly connected with a filter screen plate 13, the filter screen plate 13 filters a water sample about to flow to the water taking hole 21, the amount of solid impurities with large volume entering the sampling barrel 1 is reduced, and the possibility of blocking the water taking hole 21 caused by the solid impurities is also reduced. The end edge of the sampling barrel 1 facing the well bottom is rotatably connected with a plurality of guide balls 14, and the guide balls 14 are arranged in an annular array by taking the axis of the sampling barrel 1 as a center. The number of the guide balls 14 in this embodiment is twelve; when the inner wall of well is uneven, lead to ball 14 and have certain probability and replace sampling bucket 1 and well inner wall direct contact to produce certain guard action to sampling bucket 1, also improved the unobstructed degree of the process that sampling bucket 1 transferred.

The implementation principle of the simple deep well exploration water taking device in the embodiment of the application is as follows:

after the suspension rope 11 is tied up on sampling bucket 1, will take sampling bucket 1 and transfer in the well, after 1 bottom of sampling bucket is immersed by the water in the well gradually, the water level of well water reachs the hole 21 department of getting water and opens water inlet plate 22 through water pressure, and the water sample is accomplished the sampling and is collected in getting into sampling bucket 1, then alright will take out sampling bucket 1 from the well through pulling suspension rope 11. When the sampling barrel 1 is lifted, liquid in the barrel has a sinking moving trend, the water sample pushes the water inlet plate 22 to seal the water taking hole 21, and the water sample collected in the sampling barrel 1 is taken out by the sampling barrel 1.

The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
