The present invention provides an integrated infiltration water intake system, as shown in fig. 1, which comprises a water delivery channel 100 arranged in a river bed and at least one water intake well 200 communicated with the water delivery channel 100 in a preferred embodiment of the present invention, wherein two water intake wells 200 are arranged in fig. 1, and the two water intake wells 200 are respectively communicated with both ends of the water delivery channel 100. The water delivery channel 100 is provided with a plurality of water intake valves 140 for controlling the on-off of the water delivery channel 100, a zero-energy backflushing pipe 150 communicated with the interior of the water delivery channel 100 is connected between two adjacent water intake valves 140 on the water delivery channel 100, and the zero-energy backflushing pipe 150 is provided with a backflushing control valve 151. The water inlet of the zero-energy backwashing pipe 150 is communicated with an external backwashing water source, the water level of the backwashing water source is higher than that of riverbed river water, the backwashing water source can be an inlet channel or a water storage device erected to a certain height, tail water of a power plant can be introduced into the zero-energy backwashing pipe 150, the height of the backwashing water source is set according to actual requirements, and backwashing on the water taking filter 110 of the water delivery channel 100 is realized by backwashing water by means of differential pressure.

At least one of the water intake wells 200 is provided with a turbidity meter 204 for detecting the turbidity of the water in the water intake well 200 and a water level meter 205 for detecting the water level in the water intake well 200, for example, the left water intake well 200 is provided with the turbidity meter 204 and the water level meter 205, and the right water intake well 200 is not provided with the turbidity meter 204 and the water level meter 205. The signal output ends of the turbidity meter 204 and the water level meter 205 are electrically connected with the signal input end of a controller (not shown in the figure), the water taking control end of the controller is electrically connected with the enabling end of the water taking valve 140, and the backflushing control end of the controller is electrically connected with the enabling end of the backflushing control valve 151.

In the present invention, the aquifer a is a sandy gravel aquifer of a river bed, a riverbed, a lake bed, a reservoir, or the like. In the water intake system, surface water is filtered by the aquifer a and then enters the water intake filter 110, is collected by the water delivery channel 100 and enters the water intake well 200, and is pumped out by the water pumping pump set. By the action of pressure conduction, a pressure difference is generated between the river water level and the water intake well 200 water level, a low pressure region is formed in the aquifer a, and the submerged water seeps into the water intake filter 110 of the water delivery passage 100.

When the turbidity meter 204 measures that the turbidity value of the water in the water intake well 200 is lower than a set value (lower than the turbidity value of normal drinking water, the specific value is set according to the actual condition), and the water level meter 205 measures that the water level of the water intake well 200 is lower than the set value (lower than the minimum water level of the water intake well 200), it indicates that the water intake filter 110 is blocked, the pore diameter of the water intake filter 110 is reduced, the water yield is reduced, meanwhile, the filtered water quality is better, and the turbidity of the water is reduced. At this time, the controller controls the water taking valve 140 to be closed, and simultaneously controls the backflushing control valve 151 to be opened, so that water at a backflushing water source enters the zero-energy backflushing pipe 150, the water taking filter 110 is backflushed by utilizing the pressure difference formed by the height difference between the backflushing water source and the river water, the clogging of the water taking filter 110 is eliminated, and the water yield of the water taking well 200 is increased.

It should be noted that, in practice, compressed air may be introduced into the water intake filter 110 through the zero-energy backwashing pipe 150, and the compressed air in the water intake filter 110 may backwash the blockages in the sandy gravel layer around the water intake filter 110, thereby removing the clogging in the water intake filter 110.

In this embodiment, the water intake valve 140 and the backflushing control valve 151 may be water-controlled, air-controlled or electric-controlled valves in the prior art.

In the present embodiment, the water delivery passage 100 is provided in the aquifer a in whole or in part, and the water intake filter 110 is provided in whole or in sections in the part of the water delivery passage 100 provided in the aquifer a, and specifically, the aperture and installation length of the water intake filter 110 are set according to the water production demand. For example, when the water delivery passage 100 shown in fig. 15 is partially disposed in the aquifer a, the part of the water delivery passage 100 located outside the aquifer a is a water intake filter or a barrel-shaped structure without holes on the whole body, and the invention is not particularly limited.

In the present embodiment, as shown in fig. 2 to 4, both ends of the water delivery passage 100 are located at the same side of the river bed or at both sides of the river bed, respectively. The number of the water taking wells 200 is one, two or more, and two or more water taking wells 200 are arranged at the same side or opposite sides of the river bed. The water intake well 200 may be a water collection well, or a transmitting well or a receiving well for constructing the water delivery passage 100.

In the present embodiment, the water intake filter 110 is made of stainless steel, and is a backflushing type filter, which may be one or a combination of several of a backflushing type gravel packing filter disclosed in CN201738372U, a rotary automatic cleaning backflushing filter disclosed in CN206198831U, and a gravel packing backflushing type filter disclosed in CN 206483202U. Other prior art filters having an effective porosity of 35% to 40% may of course be selected.

As shown in fig. 1 to 4, in another preferred embodiment of the present invention, the water transportation channel 100 is disposed in a curved manner in the riverbed, and particularly, the water transportation channel 100 can be flexibly disposed according to the situation of aquifer thickness development, planar distribution, etc., for example, the path of the water transportation channel 100 can be a straight line, a curved line, a spiral line, a wavy line, etc.

The curved water delivery channel 100 can be more flexibly adapted to the distribution characteristics of the change of the thickness of the aquifer, particularly to a non-horizontal aquifer structure, so that the aquifer on the upper part of the water taking filter 110 is always in the optimal thickness of the aquifer, and the water taking amount and the filtering effect (water quality) of the unit length are both superior to those of the water delivery channel 100 which is linearly arranged.

The water taking system is applied to a multi-element riverbed structure, has stronger adaptability and more obvious improvement on water quality. The multi-element riverbed structure is the stratum which forms the riverbed, and has the conditions of a water-bearing layer (one or more layers) and a soil layer (one or more layers). The linearly arranged water delivery channel 100 cannot flexibly adapt to changes of aquifers and soil layers, the situation that the water taking filter 110 simultaneously penetrates through the soil layers and the aquifers is easily caused, adverse effects are caused on water quality and water quantity, and the mode of the curve arranged water delivery channel 100 can flexibly adapt to the situation.

The water taking system is applied to riverbeds in karst (dissolving tank) areas, and has stronger adaptability. The riverbed aquifer is characterized in that the aquifer is distributed in a plurality of strip-shaped deep grooves, has large depth and is continuous. Usually, such a stratum is a multi-element structure, the traditional way of linearly arranging the water delivery channel 100 has poor adaptability and great engineering difficulty, however, the water taking system can be arranged into the curved water delivery channel 100 along the trend of the dissolving tank, and the problem of troublesome water taking can be solved.

In the present embodiment, as shown in fig. 5 and 6, the two adjacent water intake filters 110 are flexibly connected to each other by the bellows 120, and both ends of the bellows 120 are respectively fixedly connected to the two water intake filters 110, so that a certain degree of bending deformation can be achieved between the two adjacent water intake filters 110, the movable displacement of the connection between the water intake filters 110 can be achieved, and the flexible installation of the water delivery passage 100 is facilitated. The bellows 120 is made of steel or rubber, and preferably, an end surface of the bellows 120 is hermetically connected to an end surface of the water intake filter 110, so that the sealing property between the water intake filters 110 is secured.

According to the invention, the corrugated pipe 120 is arranged between two adjacent water taking filters 110, and the corrugated pipe 120 absorbs deformation, so that a certain degree of bending deformation can be realized between the two adjacent water taking filters 110, and the water taking device is suitable for application under specific working conditions, such as turning of a water taking tunnel or bending deformation of the tunnel due to external force.

As shown in fig. 5 and 6, in another preferred embodiment, a plurality of limiting units 130 are further disposed between two adjacent water intake filters 110 to prevent the corrugated tube 120 from being damaged due to excessive tensile deformation, the plurality of limiting units 130 are uniformly distributed in the circumferential direction around the center of the corrugated tube 120, the number of limiting units 130 shown in fig. 7 is six, and the number of limiting units 130 can be set according to actual conditions.

Specifically, as shown in fig. 5 to 7, the limiting unit 130 includes fixing blocks 131 respectively disposed on inner walls of the two water intake filters 110, and the fixing blocks 131 are integrally formed with the water intake filters 110 or are separately disposed and then fixedly connected to each other. The fixing blocks 131 are provided with through holes 1311, the through holes 1311 are strip-shaped holes, a connecting rod 132 is inserted into the through holes 1311 of the two fixing blocks 131, and the connecting rod 132 is movable in the through holes 1311, for example, the connecting rod 132 can move in the through holes 1311 in the axial direction and the radial direction relative to the bellows 120.
