Description

Foreign matter pickup device in liquid nitrogen tank Technical Field The utility model relates to the technical field of pickup devices, in particular to a foreign matter pickup device in a liquid nitrogen tank. Background The liquid nitrogen tank is used as an important device for storing liquid nitrogen, and is widely applied to various fields of medical treatment, scientific research, biological engineering and the like. During the long-term use of the liquid nitrogen tank, foreign matters inevitably fall into the tank. The sources of these foreign materials are various, and may be tools or container fragments that inadvertently fall during sample storage or may be fragments of the structural components in the canister that age and fall. At present, the method for cleaning the foreign matters in the liquid nitrogen tank has a plurality of defects, the traditional method usually uses simple tools such as long tweezers, a bailer and the like to pick up the foreign matters in the liquid nitrogen tank, however, the operation view of the inside of the liquid nitrogen tank is limited, the foreign matters in the tank are difficult to effectively pick up, the cleaning efficiency is low, and therefore, the in-tank pick-up device is considered to be designed so as to be convenient for picking up the foreign matters in the tank, and in view of the problems, the in-tank foreign matters pick-up device is proposed. Disclosure of utility model The utility model aims to solve the defects in the background art and provides a foreign matter pickup device in a liquid nitrogen tank. In order to solve the technical problems, the utility model adopts the following technical scheme: foreign matter pickup apparatus in liquid nitrogen container jar includes: The collecting shovel bin is used for accommodating picked objects, and a middle shaft lever is fixedly arranged at the axis; the sleeve rod is rotatably arranged on the middle shaft rod; And the picking assembly is used for cleaning objects to be picked up in the tank and is arranged at the bottom end of the sleeve rod. Preferably, one side of the collecting shovel bin is provided with an opening, and a slope shovel edge is arranged at the position of the opening bin edge. Preferably, the pick-up assembly comprises a horizontal plate with a connecting hole at one end, and the sleeve rod is coaxially arranged at the connecting hole; The scraping unit is detachably arranged at the bottom of the horizontal plate and comprises a supporting plate with bristles arranged at the bottom. Preferably, the upper side plate surface of the horizontal plate is provided with an installation groove for detachably installing an inverted U-shaped cover plate, and the inverted U-shaped cover plate is provided with a lamp strip; and the inverted U-shaped cover plate is provided with a chute for enabling the light source of the lamp strip to irradiate outwards. Preferably, the bottom of the horizontal plate is provided with a slot, and the top end of the supporting plate is fixedly connected with an inserting block which is used for being inserted into the slot. Preferably, the upper end of the sleeve rod is provided with a rotating head. Compared with the prior art, the utility model has the beneficial effects that: This foreign matter pickup device in liquid nitrogen tank jar, laminating jar body structure can realize picking up subassembly pivoted effect through the sleeve pole, can cover the bottom space entirely, picks up the action simple high-efficient, is convenient for observe jar interior environment, can effectively clean and pick up the foreign matter.
