The invention relates to the technical field of hydraulic flood prevention, in particular to a slope protection device for hydraulic flood prevention. Comprising a support frame; the protection plate is hinged to the supporting frame, and the protection plate is used for preventing water flow from impacting the slope surface; the rotating frame is hinged to the supporting frame, the rotating frame is connected with a sliding block in a sliding mode, and the sliding block is hinged to a connecting rod; the guide frame is fixedly connected to the supporting frame; the push plate is arranged on the connecting rod, the push plate is connected with the guide frame in a sliding mode, and the push plate is used for applying downward force to the connecting rod by means of resistance generated when the push plate pushes water flow to move. When water flow impacts the protection plate, the protection plate is driven to rotate to buffer the impact force of the water flow, meanwhile, downward force is applied to the supporting frame through resistance generated when the push plate moves in water, reinforcing of the connecting position of the supporting frame and the ground is achieved, and therefore the probability that connection between the supporting frame and the ground is loosened is reduced.

A plurality of arc-shaped posture adjusting bodies are distributed on the periphery of the central floater in a circular array mode, the two ends, in the length direction, of each arc-shaped posture adjusting body are connected with rotating shafts which are coaxial, and the arc-shaped posture adjusting bodies can rotate around the axes of the rotating shafts at the two ends of the arc-shaped posture adjusting bodies. The light tracking function is achieved on the basis of wind wave resistance.

This invention discloses a flexible, wave-resistant, floating photovoltaic system, including a photovoltaic platform frame. A photovoltaic power generation platform is located on the upper side of the photovoltaic platform frame, and a central float is coaxially positioned below the photovoltaic platform frame. The central float is fixedly connected to the photovoltaic platform frame via a float support. Around the central float, several arc-shaped attitude adjustment bodies are arranged in a circular array. Each arc-shaped attitude adjustment body has two ends connected to coaxial rotating shafts along its length, allowing it to rotate around the axes of its two ends. In addition to being wave-resistant, it also has a light-tracking function.

The utility model relates to the technical field of toilet deodorization, in particular to a hydraulically-driven water separation device which comprises a mounting seat and a valve, and the mounting seat is provided with a deodorization air channel and a water outlet channel which are communicated through an air inlet; the valve is rotationally arranged in the water outlet channel and comprises a control part and an opening and closing part, and the control part is used for controlling the valve to rotate under hydraulic drive of water flow in the water outlet channel, so that the opening and closing part closes the air inlet; and when the water flow in the water outlet channel stops, the opening and closing part is used for driving the valve to rotate under the action of gravity, so that the opening and closing part leaves the air inlet. The valve is arranged in the water outlet channel, the valve is driven by water flow in the water outlet channel to close the air inlet, and the valve is reversely driven under the gravity action of the body to enable the opening and closing part to leave the air inlet; therefore, when water flow exists in the water outlet channel, the air inlet can be closed to prevent the water flow from entering or partially entering the deodorization air channel to cause water inlet damage of the deodorization fan, and the hydraulic driving structure is sensitive in response, accurate in control and more reliable in work.

The invention provides a refrigerator fresh-keeping device, a refrigerator fresh-keeping method, a health management method and a refrigerator, the refrigerator fresh-keeping device comprises a plurality of fresh-keeping cabins, one of the fresh-keeping cabins comprises a low-humidity storage box, and the low-humidity storage box is provided with a condensation water collection module; wherein one fresh-keeping cabin comprises a humidification storage box, an atomization module and an air outlet module, the humidity in the storage box is reduced through the condensation water collection module, the humidity in the storage box is increased through the atomization module, and the humidity in the storage box can be stabilized through the air outlet module. Through multi-cabin independent humidity accurate regulation and control, a differential sterilization and odor removal strategy, a low-oxygen / vacuum multi-element fresh-keeping mode and other multi-element fresh-keeping modes, full-range humidity self-adaptive regulation and control are achieved, an exclusive fresh-keeping environment can be created according to different food material characteristics, and the technical problems that a traditional refrigerator is extensive in humidity control and poor in fresh-keeping effect are solved.

This utility model discloses an electronic valve and a refrigeration device, relating to the field of refrigeration control technology. The electronic valve includes a valve body, a valve needle assembly, and a guide sleeve. The valve body has a valve cavity, a connecting port, and a valve port communicating with the valve cavity. The valve needle assembly includes a mounting base and a valve needle. The mounting base is fixedly connected to the valve body, and the valve needle movably passes through a mounting hole in the mounting base to open and close the valve port. The guide sleeve is fixedly installed inside the valve cavity, located on the side of the mounting base facing the valve port and spaced apart from the mounting base. The guide sleeve has a guide hole for the valve needle to pass through. By placing the guide sleeve on the side of the valve needle assembly near the valve port, not only is the movement of the valve needle guided, but the impact area of ​​the refrigerant on the valve needle head is also reduced, thereby reducing the vibration amplitude of the valve needle and thus reducing the resulting noise. The spaced arrangement between the guide sleeve and the mounting base makes the assembly of the guide sleeve independent of the positional accuracy of the valve needle assembly, simplifying the assembly process and reducing manufacturing difficulty.
