The dam 005 is used as the core of the whole spur dike, and at least one dam 005 is included in the river channel. In a preferred embodiment, a plurality of said dams 005 are built in the river to form a spur dike group, so as to improve the control effect on the water permeability.

The dam body 005 is perpendicular to the river bank 011 and is fixed on the riverbed 012, one end of the dam body is inlaid on the river bank and is arranged in a T shape with the river bank, the dam body and the riverbed form an angle of 90 degrees, and the length of the dam body is 1/4-1/2 of the riverway according to actual conditions.

The river bank 011 excavates a bank slope on the basis of a natural river bank, piles up broken stones and pours the broken stones by concrete; in a water level fluctuation area, the river bank 011 is vertically arranged on a river bed 012; the riverbed 012 is smoothly connected with the river bank 011 after being excavated and leveled.

In this embodiment, the controller 003, the storage battery 002 and the plurality of water turbines 004 are arranged in the dam body along the dam root towards the dam head direction, the storage battery and the controller are arranged at the innermost side of the dam body, and the storage battery is arranged above the controller; among the multiple hydraulic turbines, two that the size is the same stack in the dam body for a set of, each hydraulic turbine unit sets gradually and the hydraulic turbine size increases gradually along the dam root to dam head direction, and the hydraulic turbine size that is close to dam head department is the biggest, and except leaving behind the necessary construction joint, the height of single hydraulic turbine casing approximately accounts for 1/2 of dam body height.

The signal processor 001 may transmit the received electrical signal to the controller 003, and the controller 003 analyzes and processes the information transmitted by the signal processor.

The thickness of the water turbine shell of each water turbine 004 is consistent with that of the dam body.

In this embodiment, the structure of the water turbine is shown in fig. 4 and 5.

The runner mainly comprises water turbine blades 006 and coils 007, the coils are arranged in the middle of the water turbine blades and connected with the water turbine blades, and a layer of filter screen is arranged on each of the front outer side and the rear outer side of each water turbine, so that aquatic plants can be prevented from winding the water turbine 004; the water wheel opening and closing gate is arranged outside the rotating wheel, tracks are arranged on the upper side and the lower side of the water wheel opening and closing gate, and the gate is opened and closed in a parallel push-pull mode.

The outer part of the water turbine shell is square, and a hollow cylinder body for installing the coil 007 and the water turbine blade 006 is arranged in the square; the hydraulic turbine comprises 4 water wheel blades, the water wheel blades are arranged into an arc shape and are connected with the middle coil 007, the top end surfaces of the water wheel blades are arc surfaces, and the arc surfaces are close to the hollow cylinder.

In the present embodiment, the structure of the battery is shown in fig. 6.

The secondary battery 002 includes a battery pack 010 and a connection wire. The battery pack mainly comprises 4 batteries which are respectively fixed in four quadrants in the battery pack, and each battery is connected with the rotating wheel of each water turbine 004. The electric wire and the battery pack are wrapped by waterproof materials and then fixed on the storage battery, so that dangers such as water flow damage, electric conduction and the like are prevented.

According to the equation of continuityQ = vAIt can be known that flow is the inverse ratio with the area of crossing water at a certain time velocity of flow, and when the low water level of dry season need reduce the area of crossing water, the monitor can close water wheels through cell-phone terminal and open and close gate 008, and this spur dike structure only plays the effect that traditional spur dike restrainted water and attacked sand this moment.

Similarly, when the water level is higher in the rich water period and the river channel water passing area needs to be increased, the water wheel opening and closing gate 008 is opened, water flow can pass through the water turbine 004 at the moment, and the spur dike structure plays a role of a water permeable spur dike at the moment; therefore, the spur dike structure can adjust the opening range of the water wheel opening and closing gate according to different water levels, can play the role of controlling the water level of a river channel to the maximum degree and can reasonably utilize water energy.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
