Dam-free self-purification water taking device for field water source point

Abstract

The invention discloses a dam-free self-purification water taking device for a field water source point. The dam-free self-purification water taking device for the field water source point comprises the field water source point and a water pool arranged in the field water source point, the water pool comprises a pool bottom, two connecting side walls, an upstream side wall and a downstream side wall, the pool bottom is anchored to the bottom of the field water source point through rivets, a sand discharging pipe, a sand discharging valve, a sand discharging pump, a water taking pipe, a water taking valve and a water taking pump are arranged on the connecting side walls, the sides, facing the upstream of the field water source point, of the two connecting side walls extend outwards to formflow guide walls correspondingly, protruding flow guide strips are arranged on the outer sides of the upper ends of the connecting side walls and the corresponding flow guide walls, the opening of thewater pool is oblique, a sieve plate is arranged at the upper end of the water pool, and the sieve plate is provided with multiple rows of water leakage holes in the water flow direction of the fieldwater source point. According to the device, damming and water interception are not needed, the maintenance cost is low, a water source is kept clean and stable, dam-free self-purification water taking can be normally conducted on the field water source point for a long time, and remarkable economic value and social value are achieved.

Description

technical field [0001] The invention relates to the technical field of field water intake equipment, in particular to a dam-free self-purifying water intake device for field water sources. Background technique [0002] The distribution of my country's water resources is unbalanced, and the vast majority of water resources are concentrated in mountainous areas. Strengthening the development of water resources in mountainous areas will have a great impact on the development of agriculture, electricity, and tourism in mountainous areas. In addition to groundwater, the water resources in mountainous areas mostly exist in the form of lakes, ravines, streams, and rivers in the wild. At present, the water intake methods for these wild water sources are mainly through the construction of barrages and the installation of straight-grid filter screens. , sedimentation tanks, etc., but due to the limitations of the field climate and natural conditions, there are the following problems: ...

Problems solved by technology

In addition to groundwater, the water resources in mountainous areas mostly exist in the form of lakes, ravines, streams, and rivers in the wild. At present, the water intake methods for these wild water sources are mainly through the construction of barrages and the installation of straight-grid filter screens. , sedimentation tanks, etc., but due to the limitations of the field climate and natural conditions, there are the following problems: First, with the change of seasons, especially in autumn and winter, trees will produce a lot of fallen leaves and dead branches, coupled with gravel, mud There are many sundries such as pollution, it is difficult to ensure the cleanness and stability of the water source, and at the same time, it will often cause blockage to the filter screen, affecting the normal operation of water intake; the second is that China's climate changes greatly, especially in the rainy season, due to the sharp increase in water volume, often There will be a certain amount of floods, and the barrage is in danger of being washed away by the flood; third, the structures of water intake facilities such as barrages, filters, and sedimentation tanks are complex, and the construction work is relatively large. In order to ensure the long-term smooth operation of water intake, these Maintenance of water intake facilities, high cost of water intake
