The utility model provides a sprinkling irrigation device, comprising: a sprinkling irrigation pipe group comprising a water inlet pipe and a water spray pipe, the water inlet pipe being communicated with the water spray pipe; the adjusting assembly is connected with the water spraying pipe and used for adjusting the pitching angle of the water spraying pipe; the valve is arranged on the water inlet pipe or the water spraying pipe; and the controller is used for controlling the adjusting assembly and the valve, so that the pitching angle of the water spraying pipe is matched with the opening degree of the valve.

This invention relates to the field of gas water heater technology, and particularly to a control method for a zero-cold-water supply system, the zero-cold-water supply system, and an H-type water valve. The control method for the zero-cold-water supply system includes the following steps: obtaining the operating position of the circulation pump based on the inlet water temperature T_in, ambient temperature T_amb, return pipe length L1, the number of working check valves A1, and the hot water setting input by the user; determining the outlet water temperature T_out and the set temperature T_set corresponding to the hot water setting; if the outlet water temperature T_out ≥ the set temperature T_set, the circulation pump stops, and the preheating stage ends; if the outlet water temperature T_out < the set temperature T_set, the circulation pump continues to operate at the current operating position, or the circulation pump adjusts its operating position and continues to operate. This control method for the zero-cold-water supply system avoids the cross-flow problem caused by the check valve in the H-type water valve getting stuck, ensuring the stability of the zero-cold-water supply.

The utility model discloses a switching type water spraying assembly, which is arranged on the side wall of a ceramic basin, is used for switching a water outlet function, and is characterized by comprising a water outlet body and a switching mechanism, the water outlet body covers the side wall of the ceramic basin; the water outlet body is provided with at least two water spraying cavities, and the two water spraying cavities extend in the length direction of the water outlet body and are distributed up and down in parallel; the switching mechanism is arranged between the water outlet body and the side wall of the ceramic pot, the switching mechanism comprises a water guide piece arranged on the water outlet body and a water inlet piece arranged on the mounting hole in the side wall of the ceramic pot, the water guide piece is provided with two water guide ports corresponding to the two water spraying cavities, and the water guide piece is in sliding connection with the water inlet piece; according to the technical scheme, the water spraying device is simple in structure and convenient to manufacture, the mode that an existing water spraying device adopts a plurality of control switches to switch the water outlet function is abandoned, and the problems that the existing water spraying device is unstable in function and poor in use experience feeling are solved.

The utility model discloses a flow guide device and dish-washing machine relates to dish-washing machine technical field. It includes flow guide board and baffle, and flow guide board installs in the water inlet of the backwater pump of dish-washing machine, with the flat filter of dish-washing machine, to even washing water flow's flow rate through flat filter. Baffle is connected with flow guide board, and baffle sets up between the microfilter and water inlet of dish-washing machine, to reduce washing water flow's flow rate through microfilter close to the area of water inlet. The setting of flow guide board can reduce the water flow after passing through flat filter filter, and the residual amount of food residue in the filter screen aperture of flat filter. So that more water quantity washing water flow flows into the inside of filter from the top of flat filter. Through baffle can avoid the area that microfilter is close to the water inlet of backwater pump forms the high-speed flow area of negative pressure, causes food residue to easily follow the situation of high flow washing water flow and washes and embeds the filter screen aperture of microfilter.

The invention provides an in-reservoir gate applied to a submersible type hydroelectric power station, and relates to the technical field of water conservancy gates, the in-reservoir gate comprises a partition cement board, the partition cement board comprises a partition board body, an unfolding groove is formed in the outer surface of the partition board body, and a supporting seat is fixedly connected to the top of the partition board body; a transmission cavity is formed in the top of the partition plate body, and a supporting cavity is formed in the bottom of the transmission cavity. By arranging the transmission chain, the first transmission gear drives the second transmission gear to rotate, the two ends of the two gates are fixedly connected to the connecting shafts of the upper transmission gear and the lower transmission gear correspondingly, and therefore synchronous opening and closing of the first gate body and the second gate body are achieved; by arranging the first gate body and the second gate body which are synchronously unfolded, the water flow of river water rises faster when the gates are opened for draining water, the water flow of the river water drops faster when the gates are closed, the problem that deposited silt can not be washed away thoroughly is solved, and the overall surrounding environment can be improved.
