The utility model discloses a concrete scheme as follows: an oil tank sampling device comprises a sampling bottle, the sampling bottle is also matched with a bottle plug and a limiting structure, a stay cord is fixed on the bottle plug, the bottle plug is used for sealing an outlet of the sampling bottle, the sealed sampling bottle can sink into the liquid level of the oil tank in an empty bottle state, the stay cord can be lifted to open the bottle plug, the stay cord is used for driving the sampling bottle to move up and down, the limiting structure is used for keeping the stay cord connected with the sampling bottle after the bottle plug is separated from the sampling bottle, the designs are introduced in CN201620903683.6, and detailed description is not given here, the improvement of the utility model is that an end cap is added, and the end cap is positioned in the sampling bottle and can float on the liquid level; magnetic attraction exists between the plug and the outlet of the sampling bottle, and a position exists between the plug and the sampling bottle when the plug floats upwards in the sampling bottle, so that the plug and the outlet of the sampling bottle are magnetically adsorbed to seal the outlet of the sampling bottle.
As a specific embodiment of the present invention, the density of the plug is lower than the density of the liquid in the oil tank.
As a specific embodiment of the present invention, a hollow sealing cavity is built in the plug.
The magnetic attraction between the upper part of the plug and the outlet of the sampling bottle can be realized by arranging a magnet block at one position in the outlet of the plug or the sampling bottle, arranging an iron block at the other position or manufacturing the iron block by adopting iron, or arranging the magnet block and the iron block at the same time.
As a specific implementation manner of this embodiment, in order to facilitate installation, the sampling bottle includes an upper portion and a lower portion, and the upper portion and the lower portion are hermetically connected after the plug is placed.
As a specific implementation of the utility model, the upper portion inner wall of sample bottle is from upwards reducing gradually and forming the horn mouth type down, and the medial surface at sample bottle top promptly is the conical surface, the up end of end cap makes both can paste tightly sealed completely with this conical surface cooperation.
Compared with the prior art, the method has the following advantages: the utility model discloses an oil tank sampling device, built-in end cap that can float in its sampling bottle, the back self-closing sampling bottle export is filled with to liquid, consequently, there is not the fluid exchange inside and outside the sampling bottle lifts the in-process bottle, can ensure that the sample is the true sample under this liquid level condition.

Detailed Description
The present invention will be described in further detail with reference to the following examples and drawings, but the present invention is not limited thereto.
Examples
Referring to fig. 1 to 2, fig. 1 is a schematic overall structure diagram of the oil tank sampling device according to the embodiment, and fig. 2 is a sectional view of fig. 1.
The utility model provides an oil tank sampling device, includes sampling bottle 1, and sampling bottle 1 still is supporting to have stay cord 2, bottle plug 3, limit structure 4 and end cap 5.
Stay cord 2 and 3 fixed connection of bottle plug, bottle plug 3 is used for sealed sampling bottle 1 export, sealed back handheld stay cord 2 can be with empty bottle with sampling bottle 1, the oil tank is put into to the encapsulated situation, sampling bottle 1 sinks under the liquid level under self action of gravity, of course, if sampling bottle cavity part probably floats on the liquid level when being big, can make it sink under the liquid level through increasing the counter weight this moment, after sampling bottle 1 reaches the target depth, lift stay cord 2 hard and can open bottle plug 3, the position of target depth can be calculated through the length of stay cord 1 release.
Limiting structure 4 is the spacing with sample bottle 1 fixed connection, and spacing top is provided with the through-hole, and the one end of stay cord 1 is passed behind this through-hole with 3 fixed connection of bottle plug, and bottle plug 3 is greater than this through-hole, consequently, stay cord 2 still is connected with sample bottle 1 after 3 and the separation of sample bottle of bottle plug 1, can carry out sample bottle 1 after the sample is taken out from the oil tank.
The plug 5 is positioned in the sampling bottle 1, is made of thin iron material, and is internally provided with a sealed cavity, so that the whole density of the sampling bottle is lower than that of oil, and the sampling bottle can float on the liquid level. The magnet block 101 is provided at the outlet of the sampling bottle 1, and the magnet block 101 is magnetically attracted to the stopper 5. When the bottle stopper 3 of the sampling bottle 1 is opened, oil enters the plug 5 in the sampling bottle 1 and gradually rises along with the liquid level in the sampling bottle 1, the distance between the magnet 101 and the plug 5 is gradually reduced, the magnetic force between the magnet 101 and the plug is gradually increased, finally, the magnetic force between the plug 5 and the magnet 101 is greater than the gravity of the plug 5, and the plug 5 compresses the inner side of the upper end surface of the sampling bottle 1 and seals the outlet of the sampling bottle 1.
In addition, for the convenience of installation, sample bottle 1 sets up two parts about into, places end cap 5 back upper and lower two parts sealing connection again, adopts threaded connection in this embodiment.
The upper portion inner wall of sampling bottle 5 is from upwards forming the horn mouth type of undergauge gradually, and the medial surface at sampling bottle 5 top promptly is the conical surface, and the up end of end cap 5 makes both can realize compressing tightly sealed by seamless contact completely with this conical surface cooperation.
The above description is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the embodiment of the present invention should be covered by the scope of the present invention.
