Abstract: The present invention provides a panel, a flood control assembly, a flood control device and a flood control barrier.

Abstract: An inflatable buoyant platform (100) comprising a hollow inflatable enclosure (105) having a top surface (165) and a bottom surface (170), which are being peripherally joined by a flexible curtain (175). A support means (180) being provided inside the enclosure (105), the support means (180) adopts an extended form inside the enclosure (105) to enhance the rigidity of the enclosure (105) when the platform (100) is inflated, the support means (180) adapts a retracted form inside the enclosure (105) when the enclosure (105) is deflated. At least one inflating valve (135) on the enclosure (105) for inflating the enclosure (105) by an external source of compressed gas; at least one deflating valve (145) on the enclosure (105) for deflating the enclosure by the external source of compressed gas; and at least one exit valve (185) on the enclosure (105) for allowing the compressed gas to escape while deflating the enclosure (105).

Abstract: The present invention provides a panel, a flood control assembly, a flood control device and a flood control barrier.

Abstract: The invention relates to a flood control device with direct sensing and control. The flood control device consists of a float which is connected with a flood barrier sheet and the flood barrier sheet will be pulled up by the float according to the flood water level. The flood barrier sheet is fixed at the support frame by having flaps. The flaps are filled by compressed air. The flood barrier sheet has a rounded ball shape protruding edge at four sides of the sheet which will be fully secured from slip out due to the pressure exerted from the flood water by compressed air filled flaps. The flood control device is anchored onto the ground by having a shaft (which is inserted into the hole of the bottom piece through a hard rubber ring at shaft end and groove at the bottom piece). A stand is anchored onto the ground and connected to the support frame of the flood control device with metal structure to prevent from collapsing due to force from the flood water.

Abstract: The present invention relates to a height adjustable speed bump for controlling speed of vehicles when placed on roadways and for serving as a barrier when used for blocking restricted areas. The speed bump comprises a portable body (100) having a middle portion (120) and two side portions (110a, 110b). An elevation (290) of the body (100) is adjustable in dependence upon the usage as the speed bump or the barrier. Various arrangements are proposed for adjusting the elevation (290). A sensor is also provided on the body (100), for tracking the number of objects such as vehicles, passing over it. Methods of using the bump and barrier are thus proposed.
