This invention discloses a river water ecological restoration and purification device, belonging to the field of river water purification technology. It includes a base plate with an air cushion installed at its bottom. Above the base plate, from front to back, are sequentially arranged an ice-breaking and salvage conveying component, a collection and separation component, a water purification component, and an oxygenation component. The collection and separation component contains a vibrating filter component. A drive component is located between the ice-breaking and salvage conveying component and the collection and separation component. A propeller is fixedly installed at the rear of the base plate, and a power component for unmanned operation is installed on the top of the base plate. This invention, through its integrated ice-breaking and salvage conveying component, collection and separation component, vibrating filter component, water purification component, and oxygenation component, highly integrates multiple functional modules such as ice breaking, salvage, conveying, solid-liquid separation, water purification, and oxygenation, filling the gap left by the inability of most cleaning equipment to be used in winter and achieving uninterrupted river ecological restoration.

This invention relates to the field of seed germination devices, specifically to a seed germination device for canna lily cultivation. It includes a germination tank, a support frame positioned at the top of the tank's inner cavity, a heating mechanism positioned within the tank's inner cavity, and an aerator positioned at the bottom of the tank's inner cavity. An outer sleeve is mounted on the support frame, and an inner sleeve is located inside the outer sleeve. A first support plate with a first through hole is slidably mounted inside the inner sleeve. A high-position fixing component is positioned between the outer sleeve and the inner sleeve. This device uses the first support plate to push the seeds to a high position for temporary fixation, and after descent, the seeds fall naturally in a parabolic trajectory due to gravity. This achieves the effect of gently tumbling and repositioning the seeds without mechanical blade contact or water flow impact, effectively solving the problems of existing static soaking leading to oxygen deficiency and seed rot, and existing mechanical stirring blades causing seed tearing and embryo damage due to rigid impact.

This utility model relates to the field of water aeration technology, specifically to an integrated air-water mixing oxygenation system. It includes an oxygenation tower, which is frustum-shaped and contains an aeration chamber. It also includes a main water supply pipe for conveying water flow, with multiple oxygenation towers. Multiple branch water supply pipes are connected to the main water supply pipe and are connected to the upper part of the oxygenation tower. Furthermore, it includes an aerator for supplying airflow to the oxygenation tower, with an air supply pipe connected to the outlet of the aerator. This air supply pipe is connected to the lower part of the oxygenation tower, and a water supply pipe for supplying water to a water tank is connected to the lower part of the oxygenation tower. This integrated air-water mixing oxygenation system allows for flexible selection of the number of oxygenation towers according to the size of the water tank, achieving efficient oxygenation for large-area water tanks. The air supply pipe connects to the lower part of the oxygenation tower, and the branch water supply pipes connect to the upper part. During the descent of the water flow, it can better mix and contact with the rising air bubbles, prolonging the contact time between the bubbles and water and improving dissolved oxygen efficiency.

This utility model provides an aeration device for fish farming net cages, including a base, a water pump, an inlet pipe, an outlet pipe, a support rod, and a water tray. The inlet pipe is a flexible hose with both ends connected to the water pump outlet and the base. The outlet pipe consists of multiple rigid pipes installed inside the net cage and around the base, with the lower end of the outlet pipe inside the water and connected to the base, while the upper end is closed and extends upwards out of the water. A spray pipe connected to the outlet pipe and located above the water is installed at the upper end of the outlet pipe. The support rod is vertically fixed to the top of the base, with its upper end extending out of the water. The water tray is coaxially mounted on the support rod and located above the water. Several drainage holes are provided on the side wall of the water tray, connecting to the outside and the containment cavity. All spray pipes face the water tray and can spray water into it. This utility model adopts a three-stage aeration structure for three-dimensional aeration, achieving efficient oxygenation. The open spray pipe and water tray structure eliminates the risk of slit blockage and eliminates the need for frequent shutdowns for cleaning, ensuring continuous aquaculture.
