Abstract: The knob screen device includes a glass touch cover plate, a display screen, a screen support frame, a semi-transparent turning structure, an annular light-leading friction shim, at least one battery, a mainboard and a magnetic attraction assembly. The knob screen device further comprises: at least one Hall sensor provided on the mainboard; at least one multicolor LED ambient light provided on the mainboard; and at least one annular multipolar flexible magnet provided in the semi-transparent turning structure. The semi-transparent turning structure is connected to external component by means of the magnetic attraction assembly. In this way, the knob screen device is simple in structure, low in cost, easy to process and install and more flexible in application circumferences.

Abstract: A piling barge is disclosed by the present invention. In the piling barge disclosed, a supporting leg includes a supporting arm extended in vertical direction. Differing from the prior art, the supporting leg further includes a supporting base. The supporting base has a transverse section larger than that of the supporting arm, an end of the supporting arm is fixed with the upper surface of the supporting base. The supporting base of the supporting leg having a larger transverse section may receive support from a larger area of mollisol ground and thus provide a larger supporting force for the hull, which enables the piling barge to perform the piling operation on sea areas with mollisol ground. A piling device of the piling barge has pile frame adjusting mechanisms, such as a luffing oil cylinder, a luffing winch mechanism and a turntable, etc., which may adjust the incline angle and the position of the pile frame, therefore the working efficiency of piling operation of the piling barge can be improved.

Abstract: The invention relates to a foundation construction platform adapted for foundation construction in a beach or offshore areas. The platform comprises a platform body (1), outriggers (5) mounted on the bottom of the platform body (1), a first hoisting frame (11) and first slide rails (21) longitudinally disposed along the platform body (1), the first hoisting frame (11) having a first lifting member (31) attached to the first transverse beam (111) thereof and the first hoisting frame (11) being capable of sliding along the first slide rails (21). Without other auxiliary equipments, such as, a crane, the operations like removing or rotating a pile can be carried out to decrease the number of the auxiliary equipments on a foundation construction platform so as to reduce the operation cost of the foundation construction platform. The present invention also provides a foundation construction platform including above mentioned hoisting equipments.
