A bracing apparatus adopted for bracing an upper casing, pivotally engaged with a lower casing with electronic elements inside, of hatch-top electronic devices facilitate repairs and maintenance of the electronic elements in the lower casing. The bracing apparatus includes a first and a second linkage bar and an elastic element. The first linkage bar is remote from the pivotal joint of the upper and the lower casing, connects to the upper casing and pivotally connects to the second linkage bar. The second linkage bar connects to the lower casing. The pivotal connection end of the first and the second linkage bars is directing outwards from the neighboring sides of the upper casing and the lower casing. The elastic element connects to the upper casing abutting the pivotal joint of the upper casing and the lower casing, and the pivotal connection end of the first and the second linkage bars.

The invention discloses a ground type external-circulation double-layer curved-face curtain wall and an installation technology thereof. The ground type external-circulation double-layer curved-face curtain wall comprises a curved-face inner curtain wall body and a curved-face outer curtain wall body, wherein the curved-face inner curtain wall body is installed on a main body structure, and the curved-face outer curtain wall body is located on the outer side of the inner curtain wall body and fixed to the main body structure through an outer supporting system penetrating through the inner curtain wall body. An inner curtain wall unit body is installed between the upper and lower adjacent floors of the main body structure, the bottom of the inner curtain wall unit body is supported on a concentric rotary bottom adjusting assembly installed at the top of the lower floor, the top of the inner curtain wall unit body is fixed to a concentric rotary top adjusting assembly installed at the bottom of the upper floor, and the concentric rotary bottom adjusting assembly and the concentric rotary top adjusting assembly adjust the inclination and upward-facing angle, towards the indoor space,of the inner curtain wall unit body through a concentric rotary mode. According to the ground type external-circulation double-layer curved-face curtain wall and the installation technology thereof, the curtain wall structure is simple, the energy-saving effect of double-layer curtain-wall external circulation is achieved, the appearance visual demand of a smooth curved face is further met, the structural safety performance is good, the installation technology is easy to implement and not tedious, and the construction efficiency is high.

The invention relates to the technical field of formation of battery pole plates, in particular to a formation equipment and method for battery pole plates, including a formation pool, a connecting seat, a Z-shaped frame plate, a fixing frame and a fixing mechanism. When the present invention fixes the polar plate entering the chemical formation pool, the upper and lower sides of the polar plate are fixed by means of line contact and point contact through the supporting roller and the pressing ball on the pressing block, so that the polar plate can be fully The formation treatment avoids the problem of insufficient formation when the pole plate is fixed, and at the same time, the pole plate in the present invention is always located in the middle of the card placement frame under the guidance of the left and right inclined guide plates, thereby improving the accuracy of the pole plate placement position , when the pressing block and the pole plate continue to move downward, the push plate pushes the inclined guide plates on the left and right sides to move to both sides respectively, so that the inclined guide plate and the pole plate are separated, preventing the inclined guide plate from contacting the pole plate and affecting the pole. The plate undergoes a chemical conversion reaction.
