In the figure: 1. inserting a barrel: 101. an overflow port 102 and a limit port; 2. a lock pin; 3. a snap ring; 4. a spring; 5. a plunger seat: 501. overflow holes 502, pin holes; 6. a long rod.
The specific implementation mode is as follows:
the invention is further described below with reference to the accompanying drawings:
the technical scheme adopted by the invention for solving the technical problem is as follows: the sampler comprises: the plug comprises an insertion cylinder, a plunger seat, a lock pin, a spring, a snap ring and a long rod. The sampler inserts the cylinder into the sediment through the long rod to take a sample, and after taking the sample, the sediment can be ejected out of the insertion cylinder through the plunger seat.
The inserting cylinder is a slender thin-wall cylinder made of stainless steel and is used for being inserted into a sediment at the bottom of the cylinder for sampling. The upper part of the inserting cylinder is provided with two pairs of open holes: the pair of circular overflow ports correspond to the overflow holes of the plunger seat and are used for discharging liquid in the cylinder when the inserting cylinder is inserted downwards; the other pair of the limiting openings is a long-strip limiting opening, corresponds to the pin hole of the plunger seat and is used for limiting the lock pin.
The plunger seat is a stepped cylinder made of copper alloy materials, is vertically installed in an inner hole in the upper portion of the inserting cylinder, is used for connecting a long rod with the inserting cylinder, and can freely slide in the inserting cylinder under the unlocking condition. And a threaded hole is processed in the upper part of the plunger seat and is used for connecting a long rod. Two kinds of trompils of plunger seat lower part processing: one pin hole is a horizontal cylindrical pin hole, corresponds to the limiting opening of the inserting cylinder and is used for installing two lock pins; the other is a pair of inverted L-shaped overflow holes which correspond to the overflow ports of the inserting cylinder and are used for discharging liquid in the cylinder when the inserting cylinder is inserted downwards.
The locking pin is a pair of small stepped cylinders made of stainless steel, is horizontally arranged in the pin hole of the plunger seat, is clamped at the position limiting port of the insertion barrel under the action of a spring and is used for limiting the moving distance of the plunger seat in the insertion barrel.
The spring is a compression spring and is used for jacking the lock pin to enable the lock pin to be clamped at the position of the limiting opening of the inserting barrel.
The snap ring is a pair of small circular rings, is arranged at two ends of a pin hole of the plunger seat and is used for plugging the lock pin and the spring in the pin hole of the plunger seat. The inner hole of the snap ring is in clearance fit with the small end of the lock pin, and the outer diameter of the snap ring is in interference fit with the pin hole of the plunger seat.
The lock pin, the snap ring and the spring form a limiting mechanism of the plunger seat in the inserting cylinder.
The long rod is a long and thin steel pipe, the lower part of the long rod is provided with an external thread, and the long rod is installed in a threaded hole in the upper part of the plunger seat. The long rod is used for lowering and lifting the sampler, rigid loading during sampling is realized, and the inserting cylinder is inserted into the sediment at the bottom of the tank.
As shown in fig. 1 to 5, the method and principle of using the sampler are as follows:
when the sampler is put down from the top of the storage tank to the bottom of the contact tank through the long rod, sediment with poor fluidity or semi-dry shape pushes up the insertion cylinder, the plunger seat slides down to the lower part of the limiting port of the insertion cylinder, as shown in figure 1, the overflow hole of the plunger seat is aligned with the overflow port of the insertion cylinder, as shown in figure 2, the inner overflow channel and the outer overflow channel of the insertion cylinder are opened, liquid in the insertion cylinder is discharged out of the cylinder, and the sediment at the lower part is inserted into the insertion cylinder.
After the sampler is inserted downwards and sampling is completed, the sampler is lifted upwards through the long rod, the inserted cylinder is wrapped by sediment to prevent the inserted cylinder from moving upwards, the plunger seat slides to the upper part of the limiting port of the inserted cylinder, see fig. 3, the overflow hole of the plunger seat is staggered with the overflow port of the inserted cylinder, see fig. 4, so that the overflow channel of the inserted cylinder is blocked, negative pressure is formed in the inserted cylinder, and the sediment in the inserted cylinder is prevented from falling and is lifted out of the tank.
And when the sampler is lifted out of the tank, the lock pin is jacked to retract, the plunger seat is limited and unlocked, and the long rod is jacked to the plunger seat to jack the sediment in the insertion cylinder out of the cylinder, as shown in fig. 5.
