Abstract: The present disclosure discloses a display panel and a display apparatus. The display panel includes a substrate and at least one light-emitting structure disposed on the substrate, the light-emitting structure includes a first light-emitting element and a color conversion light-emitting element, and the first light-emitting element includes a first color light-emitting layer; and the color conversion light-emitting element and the first light-emitting element are disposed on the substrate in a stacking manner in a first direction, the first direction is a direction perpendicular to the substrate, and the color conversion light-emitting element includes a second color light-emitting layer and a third color color conversion layer disposed in the first direction in a stacking manner with the second color light-emitting layer. The present disclosure may improve light-emitting efficiency of a third color in the display panel, and improve brightness and a display effect of the display panel.

Abstract: A float-swing hydraulic support, including a top beam, shield beam, elevating frame, base, adjusting jack, two float hydraulic columns, base raising unit, advancing unit, face guard unit, telescopic beam unit, hydraulic control valve block, and a valve block support. The columns are between the top beam and base, with upper ends ball-hinged to the top beam and lower ends ball-hinged to the base; the telescopic beam unit is in the front end of the top beam, and the face guard unit is hinged to the beam unit; the upper end of the shield beam is hinged to the top beam, the lower end is hinged to the upper end of the frame; the upper end of the jack is hinged to the shield beam, the lower end hinged to the base; the ends of the advancing unit are hinged to a scraper conveyor and the base, respectively.

Abstract: The present application provides a collecting module of a lead-acid battery and new lead-acid battery and the winding displacement is simpler when collecting the status parameters of the lead-acid battery by disposing the collecting module in the housing of the lead-acid battery and the security is improved when detecting. At the same time, the data storing unit of the collecting module not only stores the collected raw data of the battery at the time of shipment from the factory, but also stores the collected status parameters of the battery in use, which facilitates the subsequent comparison between the raw data and the status parameters, a more accurate determining on the health status of the lead-acid battery and acquisition for the optimal maintenance of the lead-acid.

Abstract: The present application discloses a lead-acid system and intelligent system, the lead-acid battery system comprises a measuring and controlling module disposed in the housing of the lead-acid battery, used to collect the status parameters of the lead-acid battery in use; the measuring and controlling module comprises a first communication port; a gateway module, comprising a third communication port, a second communication port and a processor unit, the gateway module collects the status parameters collected by the measuring and controlling module by establishing communication with the first communication port of the measuring and controlling module through the first communication port thereof, to provide for the processor unit to analyze whether the status parameters are abnormal or not; the second communication port of the gateway module is used for remote communication and to send out the collected status parameters.

Abstract: A suspending hydraulic pillar includes an oil cylinder, a movable prop, a handle-valve body, a reset spring, a top cover, a bottom seat, a three-way valve, a position-limiting steel wire, and a guide ring. The handle-valve body is provided between a port of the oil cylinder port and the moveable prop. Position-limiting steel wire, a guiding ring, and an oil inlet is located on a lower part of the moveable prop. The three-way valve is provided in the handle-valve body. A dust-prevention ring and a sealing ring are provided between the handle-valve body, the movable prop, and the oil cylinder. The handle-valve body is fixed on the oil cylinder by means of a connecting steel wire. The handle-valve body does not move up and down as the movable prop telescopically extends or contracts. The suspending hydraulic has good stability, high strength and supporting force, good sealing, and high anti-erosive capability.
