Detailed Description

As shown in fig. 1-2, a surface water intake system, including raceway 1 and rotatory return bend 2, raceway 1 is fixed subaquely, be used for the low reaches water delivery, the position that is close to raceway 1 end of intaking is equipped with first bearing base 3 and first bearing upper cover 4, first bearing base 3 sets up on base 5, base 5 passes through the anchor bar and fixes at subaquely, first bearing upper cover 4 is installed to the one end of rotatory return bend 2 after installing on first bearing base 3, the one end that rotatory return bend 2 is close to raceway 1 is horizontal setting and socket joint in raceway 1, the other end of rotatory return bend 2 bends and is equipped with intake pipe 6, the angle of turning of rotatory return bend 2 is a, intake pipe 6 outer wall is equipped with engaging lug 7, engaging lug 7 passes through stay cord 8 and is connected with flotation device 9, flotation device 9 can select the flotation pontoon.

And a filter screen is arranged at one end of the water taking pipe 6 far away from the rotary elbow pipe 2. The upper water is filtered, impurities in the water are prevented from entering the water taking pipe 6 and the rotary elbow pipe 2, and the water taking pipe 6 or the rotary elbow pipe 2 is prevented from being blocked.

As shown in fig. 2, when the water level is high, the turning part of the rotary elbow 2 is driven by the floating device 9 to be in a vertical state, so that the upper water is introduced into the water delivery pipe 1 from the water intake pipe 6 for delivery; when the water level is low, the floating device 9 moves downwards, the rotary elbow 2 rotates along the axis of the water delivery pipe 1 to drive the water taking pipe 6 to rotate, the axis Y-Y of the water taking pipe 6 rotates along the rotation axis X-X of the rotary elbow 2, and therefore the height of the upper end of the water taking pipe 6 is reduced, the water taking height is adjusted according to the height of the water surface, and water can be taken from the upper layer all the time along with the change of the height of the water surface.

When the axis Y-Y of the water intake pipe 9 is in a horizontal state, the lowest surface water level is taken; when the axis Y-Y of the water intake pipe 9 and the rotation axis X-X of the rotary elbow form a vertical plane, the highest surface water level is taken.

The deflection angle a of the end of the rotary elbow 2 connected with the water intake pipe 6 is 45-90 degrees. The closer to 90 degrees, the shorter the length L of the water intake pipe 6 is, the length L is determined by the highest and lowest water level difference and the angle a, and L = (highest water level-lowest water level)/sina.

Preferably, a supporting tube 10 is arranged on the outer side of the rotary elbow 2, the supporting tube 10 is arranged coaxially with the water pipe 1, a second bearing base 11 and a second bearing seat upper cover 12 are arranged at the end of the supporting tube 10, and the second bearing base 11 is arranged on the base 5.

The support tube 10 is welded to the outer side of the swivel elbow 2, and the rotational stability of the swivel elbow 2 is improved by providing the support tube 10.
