Rivers are rainwater collection and overflowing channels in a certain range or basin, the water level fluctuates along with the change of rainfall in rainy seasons, river floods are formed when the water quantity is too large, and people generally need to arrange a water intake and a water discharge port because people need to take water from the rivers or discharge water to the rivers in daily life.
According to incomplete statistics, only on the trunk and the main first-level branch of the Yangtze river basin, nearly ten thousand water inlets and water outlets are arranged for people to produce or live, and how to reasonably and properly arrange the water inlets and the water outlets ensures that the water inlets and the water outlets can benefit and avoid harm, so that the water inlets and the water outlets are one of important contents for protecting Yangtze river.
One of the greatest risks of the conventional intake or discharge gate is that when the flood of the river rises, flood control safety may be directly affected due to untimely and improper closing of the intake or discharge gate (especially, flood control embankments are built in plain areas or estuary cities which are economically developed, the influence may be greater, a large amount of manpower and financial resources are invested in the flood season of the country to carry out flood control and rescue, all gates are key points for defense), and the conventional manual, electric and pneumatic gates are operated and managed for a long time, so that more manpower and resources are consumed, the randomness of the flood of the river is high, the gate is not available for many years sometimes, the personnel management is paralyzed, and once the flood control hidden danger is caused by untimely closing once the gate is out.
Therefore, a structure for solving the above problems is urgently needed.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Referring to FIGS. 1-3: the stepless variable automatic adjusting type gate comprises a closing system 1, a transmission system 2 and a water level adjusting buoyancy tank 3;
the closing system 1 and the water level adjusting buoyancy tank 3 are connected through a force transmission steel wire rope 2.3 arranged in the transmission system 2 and are respectively positioned on two sides of the water retaining wall 4, and a gate hole 4.1 is formed in the bottom of the water retaining wall 4;
the closing system 1 comprises a gate guide rail 1.1, a gate plate 1.2 and a water stop strip 1.3;
the gate guide rails 1.1 are positioned at the left side and the right side of the gate plate 1.2 and fixed on the water retaining wall 4, the bottom edge of the gate plate 1.2 is provided with a water stop strip 1.3,
the transmission system 2 is fixed on a fixed pivot 7 through a force transmission steel wire rope 2.3 arranged in the transmission system,
the transmission system 2 consists of a plurality of groups of movable pulleys 2.1 and fixed pulleys 2.2, the plurality of groups of movable pulleys 2.1 and the fixed pulleys 2.2 are connected through a force transmission steel wire rope 2.3,
the gate plate 1.2 moves up and down along the water retaining wall 4 at the waterside side, and the water level adjusting buoyancy tank 3 moves up and down along the water retaining wall 4 at the backwater side.
The elevation between the water level adjusting buoyancy tank 3 and the ground is not less than that of the water level line. The height difference between the water level adjusting buoyancy tank 3 and the water level line effectively prevents flood from submerging the ground, and the safety of people's lives and properties is ensured.
The gate plate 1.2 is positioned at the waterside side, and the water level adjusting buoyancy tank 3 is positioned at the backwater side. The gate plate 1.2 and the water level adjusting buoyancy tank 3 are arranged in positions to effectively prevent and control the water level of the backwater side to be relatively stable and not higher than the ground in the river water level fluctuation process.
The length of the opening of the two sides of the gate plate 1.2 extending out of the gate hole 4.1 is not less than 5 cm. The width difference between the gate plate 1.2 and the gate hole 4.1 can enable the periphery of the gate to be tightly attached to the water retaining wall, and closing and sealing are guaranteed.
The invention has the following specific working processes: the closing system 1 is positioned on the water inlet side (the side for blocking river flood or the side facing the water), the water level adjusting floating box 3 is positioned on the water outlet side (the side without blocking river flood or the side facing the water), and the gate plate 1.2 is connected with the water level adjusting floating box 3 through the transmission system 2; when the gate plate 1.2 works, a working control water level and a flow (control parameters comprise the lowest and highest possible control water level of a river on the water inlet side, the ground elevation of a protection ring on the water outlet side, a limit water level, the elevation of a water outlet bottom plate of a water intake port and the like) need to be set firstly, the water level adjusting floating box 3 senses or controls the elevation of the water level on the water outlet side, namely, the water level adjusting floating box 3 (3 in a figure) is correspondingly raised when the water level on the water outlet side is high (the weight of a floating box matched block is smaller than the buoyancy), so that the pulling force of the water level adjusting floating box 3 on the gate plate 1.2 (shown in figure 2) is reduced, and the gate plate 1.2 slides downwards under the self-weight effect to reduce the. (the connection relation and the installation mode among the movable pulley 2.1, the fixed pulley 2.2, the steel wire rope 2.3 and the fixed pivot 5 in the transmission system 2 are all the conventional installation mode and the conventional structural arrangement).
When the water level of the water outlet side is low, the water level adjusting floating box 3 is downward, the water level adjusting floating box 3 (comprising the weight of the matched blocks) pulls the gate plate 1.2 upward through the transmission system 2, and the corresponding gate plate 1.2 slides upward under the action of upward tension to increase the water passing section of the gate hole, so that the opening degree or closing of the gate plate 1.2 can be automatically adjusted, the flow of a water intake or a water outlet is also controlled, and the purpose of keeping the water quantity of the inlet (outlet) gate stable is achieved.
Meanwhile, when the river water level is high (the flood level is higher than the ground of the protection ring), the gate plate 1.2 continuously slides down to the bottom, and at the moment, the gate plate 1.2 is closed, so that flood control safety accidents and the like caused by a large amount of flood in the flood period of the river entering the protection ring of the flood bank are prevented, and the safety of lives and properties of people is ensured.
The above-mentioned parts not described in detail are prior art.
