The utility model relates to the technical field of aquatic product transportation packaging boxes, and discloses a packaging box for fresh water crab transportation, which comprises a box body and a box cover, a placing plate is arranged in the box body, a mounting groove is formed in the top of the placing plate, a limiting assembly is arranged on the inner bottom wall of the mounting groove, and the limiting assembly comprises a supporting block and a limiting frame. Limiting frames are fixed to the two sides of the top of the supporting block, a groove is formed in the top of the supporting block, and a first sponge block is placed in the groove; according to the crab storage box, the structures such as the placement plate, the supporting blocks and the limiting frames are designed, so that the placed crabs can be limited, the crabs can be placed one by one, on one hand, the situation that the crabs are disordered in the box due to shaking during transportation can be avoided, and on the other hand, the storage box is convenient to use; on the other hand, the crabs can be prevented from colliding everywhere, so that the crabs can be prevented from being damaged, and the fresh rate of the crabs transported to the destination is increased.

This application belongs to the field of battery production line technology and discloses a steam condensate recovery and utilization system and a battery production line. The steam condensate recovery and utilization system includes a first water tank, a second water tank, and a hot water supply device. The first water tank forms a first receiving cavity and has a first inlet, a second inlet, and an outlet, all connected to the first receiving cavity. The first inlet is used to connect to the steam condensate supply device in the battery production line. The second water tank forms a second receiving cavity and has a third inlet connected to the second receiving cavity. The water inlet of the hot water supply device is connected to the outlet via a circulation pump, and its water outlet is connected to both the first and third inlets. During the process of the circulation pump pumping the steam condensate from the first water tank into the hot water supply device for recycling, some of the water returning from the water outlet will enter the second water tank through the third inlet, effectively preventing the first water tank from overflowing and improving energy utilization.

The utility model provides a kind of giant grass substrate gastrodia elata cultivation device, including bottom shell, the upper side of the bottom shell is fixedly connected with cultivation shell, the inside of the upper side of the bottom shell is located cultivation shell and is provided with giant grass substrate, the inside of the bottom shell is provided with water supplement mechanism, one side of the inside of the bottom shell is equipped with water-absorbing sponge, the upper side of the bottom shell is provided with a plurality of ceramic capillary tubes. By setting ceramic capillary tube, water-absorbing sponge, water supplement mechanism and reflux structure, ceramic capillary tube is assisted by water-absorbing sponge, can continuously and evenly deliver moisture to giant grass substrate, avoid substrate local water shortage, water supplement mechanism changes water level by floating ball sensing, automatically opens or closes water supplement, ensure that there is always sufficient moisture in bottom shell to deliver, reflux structure can recycle the excess moisture in cultivation shell to bottom shell, prevent substrate ponding, to provide stable suitable humidity environment for gastrodia elata, guarantee its normal growth.
