Description

Multilayer degree of depth oil gas sampling equipment Technical Field The utility model relates to the technical field of oil gas sampling, in particular to multi-layer deep oil gas sampling equipment. Background The oil gas sampling is an important link in the oil gas exploration, development, production and storage and transportation processes, in the development process of the existing oil field, the surface of the oil field needs to be perforated and sampled, when the depth of the oil field is sampled, the gas in different depths of the oil field is sampled, and then the content of various elements is detected, so that a corresponding oil gas sampling device is needed to be used during sampling. The existing oil gas sampling device descends to the appointed depth through a lifting rope, then the gas is sampled by utilizing a sampling container, but in the sampling process, only one sampling can be performed at a time, the sampling container which is sampled once needs to be pulled out of a sampling hole to be replaced by a new sampling container to be placed into the sampling hole again for sampling when a plurality of depths are sampled, the operation is troublesome, and the multilayer depth is inconvenient to sample one by one in the sampling hole. Therefore, we propose a multi-layer deep oil and gas sampling apparatus. Disclosure of utility model The utility model aims to provide multi-layer deep oil gas sampling equipment, which solves the problems in the background technology. In order to achieve the purpose, the utility model provides the technical scheme that the multi-layer deep oil gas sampling equipment comprises a barrel, wherein a pillar is fixedly arranged in the middle of an inner cavity of the barrel, sliding grooves are formed in four sides of the outer wall of the pillar, and a resettable sliding component is arranged in each sliding groove; The outer wall of the resettable sliding component is fixedly connected with a carrier plate, an air pump is fixed at the bottom of the carrier plate, an air exhaust pipe is fixedly communicated with the tail end of the air pump, the air exhaust pipe penetrates through the cylinder body and is fixedly connected with an end plate, air exhaust holes are formed in two sides of the tail end of the air exhaust pipe, the top output end of the air pump penetrates through the carrier plate and is detachably connected with a sampling bag, and a second magnet block is fixedly arranged on the inner side of the top of the carrier plate; The top of pillar is fixed with servo motor, servo motor's transmission shaft outer end fixedly connected with connecting plate, the outer end bottom fixedly connected with dead lever of connecting plate, the tail end of dead lever is fixed with first magnet piece. Through adopting above-mentioned technical scheme, servo motor drives first magnet piece at first and rotates to one side for do not aim at any second magnet piece, with the barrel along the pipeline below in the sampling hole, then when reaching appointed position, utilize servo motor to drive the connecting plate and rotate, and then drive the dead lever and rotate, and then drive first magnet piece and rotate to one of them second magnet piece top, thereby under the principle effect that magnetism repels, promote corresponding second magnet piece to descend, thereby make the exhaust tube stretch out to the barrel downside, thereby make the exhaust hole spill, then utilize the aspiration pump to bleed, then take in the gas introduction sampling bag in, then after the unipart sampling is accomplished, servo motor drives first magnet piece and rotates to do not aim at any second magnet piece department again, then when descending to another degree of depth and take a sample, the repeated operation can.
