The invention relates to an offshore viscous oil time-divided and segmented heat injection oil extraction pipe string of horizontal wells and a method thereof. The pipe string comprises a sand control completion pipe string body composed of a central pipe string, a sand control screen pipe and a sand control packer. The bottom of the central pipe string is sequentially connected with a porous pip, N ball seats and pressure rupture disks through the free end of an oil pipe. The ball seats are provided with through holes, the diameters of the through holes of the ball seats are sequentially increased, and the outer diameters of steel balls are sequentially increased correspondingly. After being injected into the central pipe, heat media are injected into oil reservoirs through the porous pipe and the steel ball with the smallest outer diameter is cast when a target is reached; the steel ball with the smallest outer diameter penetrates through the ball seats to reach the first ball seat to close the through hole of the first ball seat; after pressure is increased to a design pressure value, the first pressure rupture disk is opened and injects heat to the ambient oil reservoir; when the design target is achieved, the second steel ball is put and reaches the second ball seat to close the through hole of the second ball seat; through successive operation, all the rupture disks in the upper part can be sequentially opened and time-divided and segmented heat injection can be achieved.

The invention discloses a rotary table used in a cooling and heating dual-purpose type ceiling fan. The rotary table comprises an upper disc body and a lower disc body, wherein the upper disc body andthe lower disc body are combined into a whole in the up-and-down direction. Dovetail grooves which are used for being capable of achieving assembly and disassembly of fan blades are formed in the periphery of the upper disc body in an array mode, and the lower sides of the dovetail grooves extend to the lower end face of the upper disc body. An annular groove which is connected with the upper sides of the dovetail grooves is formed in the upper disc body in the annular direction. A plurality of longitudinal through holes which are used for allowing studs to pass through are formed in the upper disc body and the lower disc body in the longitudinal direction, and the two ends, passing out of the corresponding longitudinal through hole, of each stud are connected with manual screwing nuts ina rotating mode correspondingly. The portion, stretching out of the upper end face of the upper disc body, of each stud is connected with a hexagon nut and the corresponding manual screwing nut in arotating mode, and the hexagon nuts and the manual screwing nuts are used for achieving installation of blades and locking of the upper disc body and the lower disc body. A hexagonal hole groove is formed in one end of each blade in the longitudinal direction. By the adoption of the technical scheme, the fan blades and the blades can be conveniently, reliably and detachably connected, and therefore the requirement for heating or cold air supplying can be met, the effect of the indoor ceiling fan can be made full use of, and the purpose that the dual functions of supplying cold air and supplying hot air are fulfilled by the ceiling fan is achieved through a detachable structure.

The invention discloses a method and device for high-throughput characterization of heat and a structure in the process of crystal material melting and solidification. The method comprises characterizing the change of heat in the process of crystal melting and solidification in real time through a differential scanning calorimetry method, simultaneously, analyzing the structural information of theprocess in real time through X-ray diffraction, and in the crystal growth process after nucleation, observing the micro-structure evolution in real time through X-ray imaging. In one experiment, heatinformation in the crystal material melting-solidification process, melt structure change information along with temperatures before solidification and solidification micro-structure evolution information such as a solid / liquid interface advancing speed and dendritic crystal morphology when solidification are obtained. The device greatly shortens the research cycle of the crystal material melting-solidification process, realizes high-throughput characterization test analysis of the process heat and structure information in the same experiment and is used for the regulation and control of crystal material properties.

The invention relates to the technical field of glass curtain walls, and discloses a heat gathering glass curtain wall used in a severe cold region. According to the heat gathering glass curtain wallused in the severe cold region, an inner metal heating heat exchange assembly comprises a plurality of transverse metal strips and longitudinal metal strips which are transversely and longitudinally arranged at intervals in a frame arrangement mode, and a plurality of heated protrusions are distributed on the sides, facing outer heat gathering glass, of the transverse metal strips and the longitudinal metal strips; a plurality of heat gathering units are integrally arranged on the outer heat gathering glass in a spaced arrangement mode, and the heat gathering units are arranged in one-to-one correspondence with the heated protrusions, so that solar energy is gathered on the heated protrusions through the heat gathering units, and in this way, concentrated energy is gathered on the heated protrusions, so that heat gathering is achieved; and the transverse metal strips and the longitudinal metal strips utilize metal heat conduction performance to realize heating and application of heat,the heat exchange efficiency of heat is improved, and the heat gathering performance is achieved.

The present invention proposes a frame-type steam rice cooker, which includes a pot liner and a frame body. The frame body includes a bearing portion, a support portion formed by extending upward from the load-bearing portion, and a top extending from the support portion to the top of the pot liner. It forms an open space for taking and placing the inner pot with the bearing part. A steam generator for introducing steam into the inner pot for cooking is arranged in the support part or the top, and a cover is provided under the top to cover the inner pot. The pot cover on the pot liner, the pot liner and the pot cover form a cooking cavity, the steam generator is connected with a nozzle, the steam ejected from the nozzle is obliquely downward towards the inner wall of the pot liner, and impacts the inner side wall of the pot liner. A tumbling steam flow is formed in the cooking cavity behind the inner wall. The steam ejected from the nozzle of the present invention first contacts the inner wall and then turns to the ingredients inside the inner pot to complete the contact with the ingredients, and utilizes the characteristic that the inner pot is a good conductor of heat to achieve uniform heating; at the same time, it can avoid local dryness and yellowing risks of.
