This application relates to a battery cell buffer mechanism. The battery cell buffer mechanism includes a fixing frame and support units. The fixing frame has at least one mounting portion extending along a first direction. At least one support unit is provided, with each support unit arranged in at least one row, and each support unit supports one battery cell. Each support unit includes at least two support members, each support member is mounted on a corresponding mounting portion and is movable relative to the mounting portion along the first direction, and each support member is used to make line contact with the corresponding battery cell for support. By making line contact with the battery cell through the support members, the risk of scratches, dust accumulation, and other adverse effects on the battery cell surface caused by the support units can be reduced. Furthermore, the ability of each support member to move relative to the extension direction of the mounting portion allows for adjustment of the position of the support members in each support unit, adapting the position of the support members to the size of the battery cell, thereby stably supporting each battery cell and improving the stability of battery cell support and the adaptability of the battery cell buffer mechanism.

The present application belongs to the technical field of sleep monitoring, and provides a sleep monitoring method and system based on adenoid hypertrophy child patients, which monitors the blood oxygen saturation of the child patients in a historical sleep monitoring period, screens out a mild hypoxia change curve, analyzes the mild hypoxia change curves in multiple historical sleep monitoring periods, obtains a target interval distance stability value, reflects the dynamic stability and trend characteristics of the mild hypoxia state of the child in sleep, helps to identify whether there is long-term fixed amplitude mild hypoxia, provides data support for evaluating the chronic effect of hypoxia on the body, and according to the target interval distance stability value, screens out a key monitoring total interval, so that the monitoring work is focused on the key monitoring total interval, the monitoring efficiency is improved, and potential long-term mild hypoxia problems of the adenoid hypertrophy child patients in the sleep process are found in time.

The utility model relates to the technical field of pressure oil tanks, and discloses a speed regulator pressure oil tank which comprises an oil tank body, a quantitative filling mechanism is arranged on the top side in the oil tank body and comprises an injection cylinder, a sliding sleeve is slidably connected to the outer portion of the injection cylinder, and a vertical plate is fixedly connected to the top of the oil tank body. A sliding frame is slidably connected to the exterior of the vertical plate, a threaded round rod is in threaded connection with the interior of the sliding frame, an extrusion round block is fixedly connected to the exterior of the threaded round rod, and an opening and closing assembly is arranged in the injection cylinder. Before filling, the threaded round rod is rotated to enable the extrusion round block to extrude the vertical plate, so that the position of the sliding frame is fixed, the amount of filled oil is read through the vertical plate, the quantitative filling effect of oil is achieved, the oil filling amount can be accurately controlled according to requirements, the stability of the oil amount in an oil tank is guaranteed, and the safety and reliability of the device are improved.

This utility model discloses a handheld seeder, belonging to the field of agricultural production. The handheld seeder includes a detachably connected upper cylinder and a lower cylinder, forming a cavity. A feeding port is provided at the bottom of the lower cylinder. A movable rod is slidably disposed within the cavity, and a sowing groove is formed on the movable rod, communicating with the cavity to hold a preset number of seeds. When the sowing groove extends beyond the feeding port, the seeds in the sowing groove are sown. This utility model allows for pressing the position of the movable rod, causing the rapeseed seeds in the cavity to be quickly sown through the sowing groove, thereby assisting workers in sowing, reducing their labor intensity, and improving work efficiency.

This invention proposes a device and method for synthesizing and concentrating L-arginine, belonging to the field of L-arginine concentration technology. The L-arginine concentration device includes a scraper assembly mounted outside a rotating shaft and a scraper assembly control structure located on an end cap at the front end of the cylinder. The scraper assembly includes a U-shaped plate body. A suction chamber is disposed on the side of the plate body closest to and parallel to the rotating shaft, and a spray chamber is disposed on the side of the plate body away from and parallel to the rotating shaft. A connecting chamber is disposed on two sides of the plate body perpendicular to the rotating shaft, connecting the suction chamber and the spray chamber. The plate body has a spray port and a suction port, and the spray chamber contains a switch column for opening or closing the spray port and a switch plate for opening or closing the suction port. This invention has the advantages of more uniform liquid distribution and higher concentration efficiency.
