The invention relates to an automatic sampler capable of sampling by simultaneously using multiple cutting rings. The automatic sampler comprises a main rod (3), an expansion rod (4) and a drill bit (7), wherein the drill bit (7) is mounted at the bottom end of the main rod (3); the automatic sampling device is characterized in that the main rod (3) is connected with the expansion rod (4) by a driving device, the driving device drives the main rod (3) and the drill bit (7) to move axially up and down, multiple clamping slots are axially formed in different positions of the main rod (3), one cutting ring is arranged in each clamping slot, and soil with different depths can be simultaneously and automatically sampled by the multiple cutting rings. The driving device drives the drill bit (7) to automatically rotate, so a traditional manpower driving mode is changed, the sampling efficiency is greatly improved, and the physical power of a sampling person can be saved.

The invention discloses a suction type membrane filtration suspended particle trap for marine environmental monitoring, and aims to provide a collection device which is convenient to operate, low in labor intensity and high in automatic degree and is particularly applicable to the process of sampling massive monitoring points respectively in different areas. The trap comprises a rack, a water pump, a traction rope, a balancing weight, a water pumping pipeline, a first diversion pipe, a second diversion pipe, a rotating shaft and two mounting casings, wherein the first diversion pipe and the second diversion pipe are fixedly arranged on the rack; the rotating shaft is arranged on the rack in a rotating manner; the two mounting casings are uniformly distributed along the circumference of the rotating shaft; a particle sampling device is arranged in one mounting casing, and a washing diversion device is arranged in the other mounting casing; one end of the water pumping pipeline is connected with the water inlet of the water pump; and one end of the first diversion pipe is connected with the water outlet of the water pump.

The invention discloses a method, a system and a computer storage medium for accurate dynamic management and adjustment of commodity sales inventory. By setting the inventory level warning value for each commodity type stored in the self-operated warehouse of an e-commerce enterprise respectively, and obtaining the current status of each commodity type Inventory, and then compare the current inventory of each commodity type with the graded early warning value of the corresponding inventory of each commodity type, so as to determine whether an early warning is required, so as to give a graded early warning to the types of commodities that need to be warned, and realize the power monitoring. The precise dynamic management and adjustment of commodity sales inventory in the self-operated warehouse of commercial enterprises has greatly made up for the existing problems of over-fixation, lack of flexibility and insufficient early warning in the management of commodity inventory in the current self-operated warehouse, and improved the comprehensive management of inventory management. The degree, flexibility and early warning strength make commodity inventory management more practical and help improve the management level of commodity inventory.

The invention provides a fast synchronizing method for small hydropower that directly compares voltage sampling values. The small hydropower includes a voltage transformer and a fast synchronization system, and the voltage transformer will collect the voltage U X and distribution network voltage U L sent to the fast synchronous system, and the fast synchronous system converts the small hydropower side voltage U X and distribution network voltage U L Compare, fast synchronous system controls the reclosing switch start of small hydropower according to comparison result; In the present invention, collection point is selected at random, has improved the reliability of method like this; By small hydropower side voltage U X and distribution network voltage U L Carry out direct comparison, when the two are close to the grid, the method is simple and convenient, and the power outage time is shortened; by judging whether a / n≥0.8 is true, this avoids the fluctuation of the voltage itself or the mismeasurement of the voltage sampling that affects the authenticity of the data .

The invention discloses a fence device for an animal floor rearing experiment. The fence device comprises frame assemblies, sealing board assemblies and U-shaped connecting parts; each frame assembly comprises a first upper cross rod, a first lower cross rod and two first vertical rods which are arranged in parallel, each first vertical rod is provided with a first through hole along the central axis, and the first vertical rods are provided with corresponding first clamping grooves; each sealing board assembly comprises a first sealing board, a second sealing board, a third sealing board and a fourth sealing board, when a fence is assembled, every two adjacent frame assemblies are connected by inserting one U-shaped connecting part into the first through holes of the corresponding first vertical rods, the two side edges of each sealing board assembly are installed in the first clamping grooves of the corresponding first vertical rods in a clamped mode, and a closed space is formed. The fence device for the animal floor rearing experiment has the advantages that the structure is simple, use is convenient, the cost is low, and the sealing property is good; fence spaces with different sizes can be flexibly assembled according to the bred animal species and the growth cycle of animals, and applicability and practicability are improved.
