The lubricating-grease automatic filling device is characterized in that the transmission mechanism comprises a guide wheel, a strong magnet, a magnetic cylinder, a cylindrical magnetic core, a connecting rod, a spiral spring and a ratchet wheel, wherein the strong magnet is arranged at the inside face of the guide wheel; the magnetic cylinder is arranged at the tail end on a bearing frame of the guide wheel and is opposite to the strong magnet; the cylindrical magnetic core is arranged in the magnetic cylinder; the connecting rod is connected with the magnetic core; the spiral spring is connected with the tail end of the connecting rod and is fixed on a bracket; the ratchet wheel is connected with the periphery of the connecting rod and is provided with a swinging rod; the speed reducing mechanism comprises a speed reducing box body, an input shaft and an output shaft; the input shaft is provided with a linear gear; the output shaft is provided with a variable-speed gear; the lubricating-grease filling mechanism comprises a cylindrical piston, an oil storage barrel and an oil filling pipe; the cylindrical piston is arranged at the end part of the output shaft; the oil storage barrel is sheathed at the periphery of the cylindrical piston and is fixed on the sliding bracket; the oil filling pipe is connected with oil filling nozzles on the oil storage barrel and the bearing frame; and the ratchet wheel is connected with the input shaft of the speed reducing box by a key, and the output shaft of the speed reducing box is in threaded connection with the oil storage barrel.

The invention discloses a display panel. The display panel includes a substrate, an organic light emitting unit and a thin film encapsulation layer. The substrate includes a display area and a non-display area, the organic light-emitting unit is arranged on the display area of ​​the substrate, and the thin-film encapsulation layer covers the organic light-emitting unit. The thin film encapsulation layer at least includes a first inorganic layer and a second inorganic layer, and the thin film encapsulation layer covers the organic light emitting unit. The display panel further includes a sealing member disposed around the display area, located between the first inorganic layer and the second inorganic layer in the non-display area, and in contact with the first inorganic layer and the second inorganic layer. Through the melting and re-solidification of the sealing member, the bonding between the first inorganic layer and the second inorganic layer and the sealing member can be strengthened, so that water vapor and oxygen in the external environment can be blocked from diffusing from the interface between the thin film encapsulation layers to the inside of the display panel, The encapsulation effect of the thin film encapsulation layer is improved, and the aging and failure of the light-emitting material of the organic light-emitting unit is avoided, thereby prolonging the lifespan of the display panel.

The invention discloses a cleaning device and a cleaning method for a solar cell panel. The cleaning device comprises a power supply, a pump, a pump tube, a cleaning storage box, a plastic hose, a cleaning barrel and a cleaning rail, wherein the power of the pump is provided by a power supply; a cleaning liquid is held in the cleaning storage box; the pump sucks the cleaning liquid form the cleaning storage box through the pump tube, pressurizes the cleaning liquid, and then conveys the cleaning liquid to the cleaning barrel through the plastic hose; the main body portion of the cleaning barrel is a holed hollow structure, one end of the main body portion is connected with the pump through the plastic hose, the other end of the main body portion is closed, and the outer surface of the main body portion is a detachable brush sleeve; the high-pressure cleaning liquid is ejected from the hole of the cleaning barrel to clean the surface of the cell panel, meanwhile, the reaction of ejecting for the cleaning liquid pushes the cleaning barrel to move along a cleaning rail. The device is capable of automatically cleaning the surface of the solar cell panel, avoiding use of a complex rail transmission mechanism, increasing the power generation efficiency of a solar power station, saving labour, improving cleaning effect, and obviously reducing operation cost.

The invention provides a feeding system of a double-chamber vacuum furnace used for thermal treatment. The double-chamber vacuum furnace used for thermal treatment comprises a front chamber and a rear chamber and is characterized in that the feeding system comprises a drive transmission device and a rising and falling device, the drive transmission device is arranged in the front chamber, and the rising and falling device is arranged at the bottom of the rear chamber and extends into the rear chamber; and the drive transmission device is used for achieving circulation, between the front chamber and the rear chamber, of thermal treatment workpieces, and the rising and falling device is used for achieving rising and falling of the thermal treatment workpieces. Compared with the prior art, a body structure of the feeding system is located outside the rear chamber of the vacuum furnace, and therefore the feeding system can be away from a high-temperature environment, and the aging failure caused by thermal expansion is avoided.

The invention discloses an elastic cushion for manufacturing an open-type rail bearing groove roadbed. The cylindrical elastic cushion comprises an attaching surface I and an attaching surface II which are oppositely arranged; and the shape of the attaching surface I is fitted with the shape of a section of the end part of a sleeper. Through the adoption of the elastic cushion disclosed by the invention, one surface of the elastic cushion is connected to the sleeper, and the other opposite surface of the elastic cushion is used for connecting a mold plate for casting a roadbed; and the elastic cushion can be bended and compressed, so that the purpose that when the sleeper is obliquely arranged, the end part of the sleeper is still tightly attached to the mold plate can be met, the purpose that no matter whether the roadbed is cast in a straight section or a curve super-elevation section, after the mold plate and the elastic cushion are disassembled, an opening in a required shape is formed in the position of the original elastic cushion, at the end part of the roadbed in which a rail bearing groove of the sleeper is formed is guaranteed, and the defects that in the prior art, if a harmful layer is not removed, an opening is not formed in the rail bearing groove, besides, the harmful layer is thin, chipping is easy to generate, if the harmful layer is removed, secondary construction is required, the workload is large, the quality is not liable to guarantee, and time and labor are wasted are avoided.. The elastic cushion disclosed by the invention is simple in structure, convenient to use and low in cost.

The invention discloses a blocking agent for a drilling liquid. The blocking agent is prepared by reaction of four raw materials: calcium lignosulphonate, sodium humate, a 20% formaldehyde solution and 2-methyl-2-acrylamido propanesulfonic acid and an initiator, wherein the mass ratio of calcium lignosulphonate to sodium humate to 20% formaldehyde solution to 2-methyl-2-acrylamido propanesulfonic acid is (30-50): (30-50): (5-15): (20-30). The blocking agent disclosed by the invention is small in particle diameter and poor in water solubility, can be effectively filled in a formation fracture to play a blocking role, and is long in molecular chain. The structure has certain elasticity and is easily filled in the formation fracture compared with the blocking agent of a rigid structure.
