Self-adaptive multi-user random water distribution head pressure and flow regulation and control device

Abstract

The invention discloses a self-adaptive multi-user random water distribution head pressure and flow regulation and control device. The self-adaptive multi-user random water distribution head pressureand flow regulation and control device comprises a water storage tank, a pressure regulation branch, a water supply branch and a pressure regulation water supply branch, wherein the pressure regulation branch, the water supply branch and the pressure regulation water supply branch are connected between a water distribution pipeline and the water storage tank; a pressure stabilization tank is arranged on the pressure regulation branch; a submersible pump connected with the water storage tank in parallel is arranged on the water supply branch; a pressure regulation submersible pump connected with the water storage tank in parallel is arranged on the pressure regulation water supply branch; and a pressure sensor and a flow sensor are arranged on the water supply branch, the pressure regulation water supply branch and the water distribution pipeline respectively. The head pressure and flow supply range can be enlarged, stable pressure can be regulated and controlled, a guarantee is provided for real-time regulation and control over the adjustable pressure stabilization tank, and water can be distributed according to the actual requirement of multi-user random water demand. Compared with a conventional regulation and control method, the pressure and flow regulation and control range is wider, and control precision is higher; and finally, pressure and flow regulation is achieved, andthe target pressure and flow of multi-user random water distribution can be achieved more accurately and rapidly.

Description

technical field [0001] The invention relates to the field of agricultural irrigation equipment, in particular to an adaptive multi-user random water distribution head pressure flow control device. Background technique [0002] my country is a large agricultural country, and agricultural water consumption accounts for 80% of the total water consumption, and the vast majority of agricultural water consumption is used for crop irrigation. However, the irrigation equipment in our country is far behind that of developed countries. The shortage of water resources has seriously affected the healthy development of local industry and agriculture, and also affected the safety of domestic water in local cities. In recent years, with the development of the national economy and society, the overall development trend of the optimal allocation and regulation of irrigation water resources is: from a single water source and a single water use department to a complex multi-water source and mu...

At the same time, the first pressure gauge is used to obtain the current pressure to maintain irrigation, so as to ensure that the moisture conditions in the soil where the crops to be irrigated are in the best state. , it is difficult to achieve the desired state in a short time;

[0007] A water-fertilizer integrated water-saving irrigation control system (2016204783081). The device includes a water-saving irrigation system, a receiver and a controller. The device is not equipped with pressure and flow control components, so the available range of pressure and flow is relatively small, so it cannot Meet the requirements of multi-user flow and pressure random changes in working conditions
