摘要:
A cryogenic full containment storage tank having a low liquid level material extraction device, comprising an inner tank (1), an outer tank (2), an operation platform (3), and a material extraction device (6) capable of extracting a low liquid level material. The material extraction device (6) comprises a material circulation tank (61) and a cryopump (65) that are installed on the operation platform (3), a first Venturi mixer (62) installed at the bottom of the inner tank (1), and connecting pipelines. The low-temperature medium in the material circulation tank (61) enters the first Venturi mixer (62) through the cryopump (65) and an inlet pipeline (63), so that the low-temperature medium in the inner tank (1) enters the first Venturi mixer (62) through the suction hole (6202) of the first Venturi mixer (62), and then enters the material circulation tank (61) through a lead-outlet pipeline (64) after being mixed.

A leading edge structure of a jet bridge floor, a jet bridge floor structure, and a jet bridge. The leading edge structure of a jet bridge floor comprises a reach assembly (1), a reach guide structure (2) and an energy storage assembly (3). Under the action of the reach guide structure (2) and an energy storage assembly (3), the reach assembly (1) is capable of extending or retracting relative to a jet bridge floor body. The reach assembly (1) can be automatically adjusted according to the location of an airplane. Due to the limiting and guiding functions of the reach guide structure (2), the reach assembly (1) assembly (1) adaptively extends or retracts relative to the jet bridge floor, thereby improving the safety of the airplane.

A system and method for aircraft docking guidance and aircraft type identification. The method is executed in the system for aircraft docking guidance and aircraft type identification comprising a machine vision sub-system, a laser scanning sub-system and a merging module. The method comprises: step 1000, the machine vision sub-system obtains an image via image capturing means, and calculates a first aircraft front wheel position therefrom; step 2000, the laser scanning sub-system obtains the position of the nose of an aircraft via laser scanning means, and extrapolates a second aircraft front wheel position; step 3000, the first aircraft front wheel position and the second aircraft front wheel position are merged according to a merging rule, and an aircraft front wheel deviation is obtained.

A freight container includes a container body (1) and corner fittings (2) provided at each corner of the container body. The container body (1) includes a bottom (10), a top (20), two side portions (30) and two end portions (40, 50), and at least one end portion is provided with locking devices (60) or corrugated plates (70). The locking devices (60) or corrugated plates (70) protrude beyond the outer edges of the corner fittings (2), and the position of each corner fitting and the distance therebetween accord with ISO standards. The inner length of the container is enlarged by extending outwards the rear end and/or the front end to the outer edges of the locking devices (60) or corrugated plates (70) beyond the corner fittings. The position of the corner fittings in the container and the relative distance therebetween are constant and accord with ISO standards, hence without influencing the alignment of the sling fitting and the corner fittings. Therefore, the inner space of the improved container is enlarged and the improved container still adapts to the existing standard products. Compared with the prior containers provided with locking bars having special structure, the present container is easy to implement and the manufacturing difficulty is small.

Disclosed are a height measurement device and a boarding bridge having same. The height measurement device has a height measurement sleeve and a distance measurement mechanism; the height measurement sleeve is vertically provided in an apparatus to be measured and comprises at least two matching sleeves; the distance measurement mechanism is provided at the bottom or top of the height measurement sleeve, wherein when a lifting mechanism of the apparatus to be measured drives the main body to lift, the height measurement sleeve stretches and lifts along with the main body or the lifting mechanism to obtain height information of the main body or the lifting mechanism according to height information of the height measurement sleeve measured by the distance measurement mechanism. According to the present invention, the distance measurement mechanism is mounted in the height measurement sleeve so as to prevent the height measurement device from being interfered by obstacles in the monitoring process, and it is not easy to produce mis-measurement phenomenon in a special environment such as rainy and snowy, so as to improve the accuracy and stability of the height measurement device.

A leveling mechanism for a passenger boarding bridge, and a passenger boarding bridge. The leveling mechanism for a passenger boarding bridge is mounted on a passenger boarding bridge (100), and comprises: a four-bar linkage mechanism and a preload apparatus. The four-bar linkage mechanism comprises a mounting base (2) which can be fixedly mounted on the passenger boarding bridge (100). One of the other three bars of the four-bar linkage mechanism extends outwards, and a leveling wheel (7) and a first detection switch (6) are mounted at the end of the bar. The first detection switch (6) is used for detecting the vertical displacement of the leveling wheel (7) on an aircraft body (500). The preload apparatus has a preload. One end of the preload apparatus is connected to the four-bar linkage mechanism, and the other end threrof is connected to the mounting base (2). The preload apparatus has a preload to make the leveling wheel (7) maintain a tendency of extending outwards. The leveling mechanism for a passenger boarding bridge has high test precision and can work reliably.
