The invention discloses a hydraulic high-efficiency water-saving toilet stool and relates to a water-saving toilet stool. The water-saving toilet stool comprises three systems, namely a main body system, a water tank system and a spray washing system. The main body system comprises a base, a tank body and a urinal; the water tank system comprises a wash-basin, a water accumulating tank and a water quality treatment tank; and the spray washing system comprises a water-saving spray washing device, a sewage intercepting and discharging device and a pedal hydraulic device. The wash-basin is positioned on the upper part of the water tank system and the bottom of the wash-basin is connected with the water accumulating tank; the bottom of the water accumulating tank is connected with the upper part of the water quality treatment tank and is communicated with the water quality treatment tank through a water feeding port; an automatic water-saving interchange valve is arranged inside the wateraccumulating tank; a plurality of layers of nano reverse osmosis filter screens and biological purification chambers are arranged at intervals inside the water quality treatment tank so as to recyclethe reclaimed water or waste water into pure water; the water-saving spray washing device is arranged on one side of the water accumulating tank and a water outlet stop valve which leads the accumulated water into the water-saving spray washing device is arranged inside the water accumulating tank; and the sewage intercepting and discharging device has the functions of directly discharging and stopping backward flowing and realizes spray washing and sewage drain through the pedal hydraulic device. The hydraulic high-efficiency water-saving toilet stool has the advantages of advanced technicalperformance, comprehensive and high-efficiency water conservation, extremely low installation and use cost, wide application and durability.

The control system comprises an equipment field control module, a sub-control platform module for a car washing station, a remote main control platform module and a third-party remote monitoring platform module. The treatment equipment and the automatic control system can be applied to the field of recycling of the car washing waste water.

The invention relates to a fluid cooling method and device. The device comprises an air cooler. The air cooler at least comprises finned tubes composed of fluid pipes and fins, wherein cooled fluid circulates in the fluid pipes, and the fins are connected with the outer sides of the fluid pipes, arranged at intervals and composed of flaky thin plates. The single side or two sides of the surface ofeach flaky thin plate are coated with a hydrophilic coating layer or hydrophilic coating layers. The flaky thin plates are in contact with circulating air. During cooling of the air cooler to the fluid, water is distributed to the finned tubes in the time frame of high atmospheric temperature, and in the time frame of low atmospheric temperature, no water is distributed to the finned tubes, or water is distributed to the finned tubes in a segmentation manner. According to the fluid cooling method and device, the surfaces of the fins are coated with hydrophilic coating, uniform and stable water films are formed on the surfaces of the fins in a wind blocking and water distribution manner, in the atmosphere high temperature time frame, water film water vaporization latent heat absorption, forced evaporation and heat exchange are directly carried out on the fins, and the cooling capacity of equipment is greatly improved. The fluid cooling method and device have the beneficial effects of being remarkable in water saving effect, low in investment cost and low in operating cost.

The invention discloses a high-efficiency water-saving valve with two-stage control. The working device is a conical water pipe (1), a conical water plug (2), and a rubber spring with variable stiffness (3). The control device is a water plug pull rope (5 ), foot pedal (6), reset rubber spring (7), auxiliary device is water valve bottom cover (4), positioning collar (8), heel shaft (9), ground pit (12), the right side of the valve It is water inlet (10), and the left side is water outlet (11). The present invention designs a two-stage control high-efficiency water-saving valve. First, it can avoid the second pollution of human hands. When washing and washing, it is not necessary to control the valve with hands, but to control the water outlet and stop water through the control device with feet; second, it can efficiently save water. Water, people can save up to 30‑50% of water when washing their hands or face with detergent; the third is to meet individual water needs, either large flow of water or small flow of water, both Water can be used for a short time or for a long time.

The invention relates to a device for solving the problem of antifreeze corrosion of silicon rectifier components, in particular to a device for solving the problem of antifreeze corrosion of silicon rectifier components by adopting two-stage cooling. It includes the primary cooler of the rectifier element, the return pipe of the primary cooler of the rectifier element is connected to one end of the first water pump, the other end of the first water pump is connected to the water inlet pipe, and the water inlet pipe passes through the plate heat exchanger for heat exchange, plate heat exchange The two ends of the heat exchange pipeline of the device are connected with the water air cooler. It solves the freezing problem of the traditional water-air cooling device of the rectifier in the cold area when the outdoor air-cooled heat exchange device freezes in case of power failure or maintenance, and ensures normal use in cold areas with harsh environments. It solves the problem that the traditional rectifier water-air cooling device corrodes the rectifier components due to the addition of antifreeze. Deionized pure water circulates in a closed environment, which ensures the quality of pure water and reduces the loss of pure water.
