The invention discloses a refrigerator which comprises a refrigerator body, a vertical beam, a guide column and an anti-collision mechanism, wherein a door body pivot shaft is connected to the front side of the refrigerator body; the vertical beam is arranged on a door body by extending in a vertical direction and rotatably mounted on one side far away from the door body pivot shaft; the anti-collision mechanism is provided with a guide groove; the guide column is movably matched in the guide groove for the convenience of moving in the guide groove to overturn or unfold the vertical beam when the door body is opened or closed; the anti-collision mechanism further comprises a guide part arranged to move left and right relative to the guide groove and first and second openings arranged to be close to the guide column and positioned on the same side of the guide groove; the first opening is used for guiding the guide column to enter or depart from the guide groove; and the second opening is used for unidirectionally guiding the guide column to enter the guide groove under the effect of the guide part. The refrigerator has the functions of two-rail closing and one-rail opening of the door body, so that a refrigerator door can be smoothly closed and better refrigerating effect can be obtained.

A refrigerator comprises a cabinet body (10), a door body (20) pivot being connected to the front side of the cabinet body (10); a vertical beam (30) arranged on the door body (20) by extending in a vertical direction and rotatablely mounted on one side far away from the door body (20) pivot; a guide column (32); and an anti-collision mechanism (42) provided with a guide groove (44). The guide column (32) movably fits in the guide groove (44) so as to overturn or unfold the vertical beam (30) by the movement of the guide column (32) in the guide groove (44) when the door body (20) is opened or closed. The anti-collision mechanism (42) further comprises a guide part arranged to move left and right relative to the guide groove (44), and a first opening and a second opening arranged close to the guide column (32) and positioned on the same side of the guide groove (44). The first opening guides the guide column (32) to enter or leave the guide groove (44), and the second opening unidirectionally guides the guide column (32) to enter the guide groove (44) under the action of the guide part.

The invention discloses a discharging device of a plastic package material. The discharging device of the plastic package material comprises a plastic package material box (1); the lower part of one side wall of the plastic package material box (1) is outwards protruded to form an outlet part (2); the top of the front end of the outlet part (2) is opened; the top of the rear end of the outlet part (2) is an inclined close cover (3); the outlet part (2) is connected with a material baffle (5) through a hinge (4); the material baffle (5) is provided with two positioning support plates (6); the hinge (4) is located between two positioning support plates (6); the hinge (4) is sleeved with a torsional spring (7); one support leg of the torsional spring (7) is located on the material baffle (5), and the other support leg of the torsional spring (7) is located on the close cover (3); a stainless steel material stopper (8) is fixedly connected in the outlet part (2); and the stainless steel material stopper (8) is located under the close cover (3). The beneficial effect of the discharging device of the plastic package material is simple structure, convenient operation and low production cost.

The invention discloses a passive waste heat discharge system based on a water cooler. By adopting an annular water cooler compactly arranged around the reactor pressure vessel, the waste heat of the reactor core is brought out, and the circulating hot water tank is divided into a hot area and a cold area. The top of the hot zone and the cold zone are in two-way communication, and the bottom is equipped with a one-way flow device to limit the flow of cold fluid from the hot zone to the cold zone, which is conducive to the discharge of water vapor through the exhaust pipe on the top and enhances the circulation of the hot water tank The natural circulation ability between the annular water cooler; the hot fluid in the water-cooled tube is used as the ascending section, and the cold fluid in the annular descending chamber is used as the descending section, relying on the potential difference and density difference of the hot and cold fluid to form a natural circulation flow, circulation The water vapor formed in the hot zone of the hot water discharge tank is discharged through the exhaust pipe on the top, realizing the safe and reliable discharge of the residual heat in the core after the normal shutdown or accidental shutdown of the reactor core, and ensuring the fuel package The temperature of the shell, pressure vessel and wall of the reactor chamber shall not exceed the allowable temperature.

The invention relates to a refractory protection used for conveying high oil stain / high dust fluid ventilation pipeline. The refractory protection is characterized by comprising a folding vane mechanism (1), a guideway (2), and a telescopic mechanism (3) which is fixed in the guideway (2); the upper end (11) of the folding vane mechanism (1) is fixedly connected with the top end of the guideway (2); the lower end of the folding vane mechanism (1) is fixedly connected with the head of the telescopic mechanism (3); the folding vane mechanism (1) comprises a plurality of vanes which are connected with each other; a plurality of middle movable ends (13) are formed by vanes which are connected end to end; the tail end of the telescopic mechanism (3) is fixedly connected with the bottom end of the guideway (2); the telescopic mechanism (3) is internally provided with a temperature sensor (4); the signal output terminal of the temperature sensor (4) is connected with the control input terminal of the telescopic mechanism; the refractory protection can form a curtain typed fireproof valve, can ensure fireproof safety and save conveying energy dissipation when conveying high oil stain and high dust fluid ventilation pipeline, and can be applied to general ventilation pipelines simultaneously.
