The invention discloses an automatic efficient pumping and recharging convertor which comprises a pipeline, wherein two ends of the pipeline retract radially; at least one pair of open pores are formed in the pipe wall; a rod object is assembled in the pipeline; the rod object is fixedly connected with a cylinder; the cylinder is in sliding fit with the inner wall; the height of the cylinder is larger than the diameter of each horizontal open pore; the lower end of the rod object is fixedly connected with a cylindrical piston; and the diameter of the cylindrical piston is larger than the inner diameter of a lower opening of the pipeline. Head pressure in a pumping and irrigation process is used for pushing the cylindrical piston to move, and bi-directional purposes of pumping and recharging can be realized by one pipeline. The head loss is small, the efficiency is high, the defect that a pump pipe loosens due to the fact that two pipes collide during recharging or re-spreading is avoided, a small diameter well can meet the recharging or pump lifting requirement, the well completion cost is reduced, attachments on the filter pipe wall can be effectively washed away under the condition that the stable state of the pump pipe is guaranteed, recharge well blocking is reduced, and the service life of a recharge well is prolonged. The automatic efficient pumping and recharging convertor can be widely applied to submerged pump connection, rain flood groundwater recharge, ground source heat pump water cyclic utilization, well repair, groundwater recharge and water supply diversion.

The invention discloses a battery management system suitable for low-temperature operation. The battery management system comprises a detection and control module, a charging and adjusting module, anauxiliary hardware module and a protection module, wherein the detection and control module comprises a voltage and current detection module and a temperature sensor assembly used for a storage battery pack; the data analysis of data signals of the detection module are performed through a control unit in the detection and control module and the data signals are compared with preset data values; the control unit transmits compared execution signals to an equalization circuit module in the charging and adjusting module; after analyzing detection data of the temperature sensor assembly, the control unit drives the operation of the auxiliary hardware module through electric signals; data information and an execution process are packed into a log file and the log file is sent to the control unit; and the control unit realizes data communication through a TTL transform interface provided by a single-chip microcomputer. The effective heating for heat preservation of the storage battery is achieved by virtue of the comprehensive detection and circuit interference of the charging and discharging process of the storage battery and by virtue of the auxiliary hardware module, so that the storage battery is maintained in a good operation condition.

The invention discloses a self-seepage and reverse-filter recharge system applied to a riverway. The recharge system comprises a recharge pool and a recharge well; a reverse-filter material is arranged in the recharge pool which is arranged at a riverway revetment; the revetment well is arranged below the revetment crest; the recharge pool communicates with the recharge well through a recharge pipeline, and a valve is arranged on the recharge pipeline; and a permeable cover plate is arranged above the recharge pool. The recharge system has a certain silt prevention function, and can prevent the reverse-filter material from being flushed away, and the emergency valve can be closed during water quality pollution to prevent polluted water from being recharged to an underground water aquifer.

An example electric lighting system includes a lighting device that includes a housing including a lighting element and a power device holding portion. The power device holding portion includes a cavity. The cavity includes a first and a second electrical contact disposed within the cavity. The power device includes a third and a fourth electrical contact. The power device includes a coupling component. The coupling component is removably couplable to the power device holding portion such that an electrical communication is established when the power device is inserted into the cavity at any rotational position relative to the lighting device about a shared central axis. The power device is operable to power the lighting device through the electrical communication. The electrical communication is established between the first electrical contact and the third electrical contact and between the second electrical contact and the fourth electrical contact.
