Abstract: The present disclosure provides an aromatherapy humidifier with a large internal water storage space and high operational safety, including a humidifier main body, an atomizing plate assembly disposed inside the humidifier main body, a turbine fan, and a main control circuit board, a spray nozzle being provided at an upper part of the humidifier main body, and further including a first LED light panel mounted at the upper part of the humidifier main body and disposed near the spray nozzle, where the humidifier main body includes a water storage tank; a blower nozzle communicating with the turbine fan is provided at the center of an upper side of an inner wall of the water storage tank; and the blower nozzle is disposed close to the first LED light panel and the spray nozzle.

Abstract: The present disclosure provides a rotary dancing aromatherapy humidifier, which includes a main machine body of the humidifier, a control circuit board arranged inside the main machine body of the humidifier, an atomizing plate sub-assembly and a rotary driving mechanism. The main machine body of the humidifier includes a water tank body, a rotating pattern ring with a grid pattern is located on the outside of the water tank body, a grid tube on the outside of the rotating pattern ring, and also includes a rotating seat for installing the rotating pattern ring; the rotating driving mechanism drives the rotating seat and the rotating pattern ring to rotate axially, and the atomizing plate sub-assembly and the rotating driving mechanism are electrically connected with the control circuit board.

Abstract: A rapidly assembled debris flow sediment storage dam and a construction method are provided. The sediment storage dam has a main dam body with multiple prefabricated reinforced concrete rectangular boxes linked by vertical and horizontal connections. The top surface of each rectangular box is open, and the other five surfaces of the rectangular box are closed. Soil is used to fill each rectangular box. The main dam body is assembled above dam body foundations. Dam abutment foundations of the sediment storage dam and the inside slope of the dam body are filled with cement-laid stone masonry or concrete, while the top surface of the dam crest is also sealed using cement-laid stone masonry or concrete.

Abstract: The invention discloses a debris-flow prevention method by controlling debris-flow magnitude and avoiding to block main river. This method first adopts the drainage works for delivering debris flow in corporation with the transport of the main river; if the drained sediment cannot be transported by the main river, the blocking works are adopted; and if the sediment still exceeds the delivering capacity, the deposit stopping works are adopted. Compared with the prior art, this invention makes full use of the main river's transport capacity, gives priority to dredging and also reasonably distributes the sediment and deploys the engineering system, so as to realize the safe discharge of debris flow, and avoid the secondary disaster of “barrier lake” caused by the blocking of main river due to excessive discharge of debris flow and fully guarantee the safety of mountain towns, major projects and infrastructure located at the mouth of debris flow gully.

Abstract: A system of debris-flow drainage canal with cascaded sills is provided, which allows a high-efficient and low-cost realization of debris flow drainage and scour prevention. The canal contains two converging walls and a series of scour prevention sills, which are laid between the two converging walls. The sills are embedded to a certain depth and are evenly spaced and symmetrical to the centre line of the canal to form a cascaded structure for scour prevention. The drainage canal's width is 2 times wider than the sill's horizontal length along the cross-section. Compared with the prior art, this system can drain off a wide variety of flows from debris flow to flood and prevent debris-flow siltation even on a gentle slope. This system has a much higher stability and longer life of service. Moreover, this system can maintain the aquatic habitat in gullies and contribute to ecological restoration.
