[0002] Water retaining dams used in water conservancy and hydropower projects play an important role in water conservancy and hydropower projects, including flood prevention and disaster reduction, runoff regulation, water supply and irrigation, aquaculture, and ensuring water resource security, etc. Among them, water retaining dams play an indispensable role in water supply and irrigation. Water retaining dams can intercept water flows, store water resources, provide sufficient water for irrigation, control water levels, and meet the water needs of different irrigation areas.

[0003] The dam is installed on the river channel and when it intercepts the water flow and forms the water level, the water level height can be monitored by detecting with a water level sensor. Secondly, the water level sensor uploads the numerical control to the control panel, and the control panel controls the motor to adjust the upper and lower heights of the gate plate of the dam, thereby adjusting the water level height blocked by the dam. However, after the water level is adjusted by the dam, it is necessary to monitor the water level height in real time to control whether the dam is closed or not. The operation is relatively cumbersome. In water conservancy irrigation, it is often necessary to control the water level at a certain height, and a certain amount of water flow must be maintained downstream for downstream irrigation. However, the existing dams are cumbersome to operate when controlling the water level, and are not simple enough.

DETAILED DESCRIPTION

[0021] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0022] like Figure 1-Figure 4As shown, the automatic regulating water conservancy and hydropower engineering water retaining dam provided in this embodiment includes a U-shaped dam body 1 with a water flow channel 101. The dam is used to be installed on a suitable river channel. A gate member 2 is installed in the water flow channel 101 of the dam body 1. Water flows through the water flow channel in the dam body 1. After being blocked by the gate member 2, the water flows converge and form a water level of a certain height. A horizontal device plate 3 is fixedly connected to the gate member 2. A gantry 8 is fixedly connected above the horizontal device plate 3. A driving component 6 is connected to the gantry 8. A movable plate 4 is hinged on the horizontal device plate 3. Both sides of the movable plate 4 are connected to the side walls of the water flow channel 101. The movable plate 4 is in contact with the dam body 1, and waterproof pads 11 are provided on both sides of the movable plate 4. The waterproof pads 11 make the contact between the movable plate 4 and the side walls of the water channel 101 tighter, so as to prevent water from leaking from the gap between the movable plate 4 and the dam body 1. A water trough 5 is provided near the middle position of the movable plate 4, and the water blocked by the gate plate 2 can flow out from the water trough 5. A driving component 6 is provided on the horizontal device plate 3. The driving component 6 adjusts the height of the water trough 5 by controlling the winding and releasing of the traction rope 7 on the output end thereof, and then controls the height of the water level of the water blocked by the gate plate 2 through the water trough 5, and the water exceeding the water trough 5 will flow out through the water trough 5.

[0023] Further, such as Figure 3 as well as Figure 4 As shown, the driving assembly 6 includes a motor 601, a driving shaft 602, a driving gear 603, a driven gear 604, a rotating rod 605 and a hinge plate 606. The motor 601 is fixedly installed on the gantry 8, the driving gear 603 is fixedly connected to the driving shaft 602, the driving shaft 602 is connected to the output end of the motor 601, the rotating rod 605 is rotatably connected to the gantry 8, the driven gear 604 is fixedly connected to the rotating rod 605, and the driven gear 604 is meshed with the driving gear 603. When the motor 601 is started, the driving shaft 602 is driven to rotate, and then the driving gear 603 is driven to rotate, and the rotating rod 605 is driven to rotate through the driven gear 604. When the rotating rod 605 rotates, the hinge plate 606 fixedly connected thereto is driven to rotate, and then the rotating rod 605 is driven to rotate. The traction rope 7 is wound on the hinge plate 606, or the traction rope 7 is released from the hinge plate 606. The hinge plate 606 is fixedly connected to the rotating rod 605. One end of the traction rope 7 is connected to the hinge plate 606, and the other end of the traction rope 7 is connected to the movable plate 4. When the hinge plate 606 winds up the traction rope 7, the rotating hinge plate 606 drives one end of the movable plate 4 to move through the traction rope 7. Because the other end of the movable plate 4 is hinged to the horizontal device plate 3, the traction rope 7 drives one end of the movable plate 4 to move upward. When the hinge plate 606 releases the traction rope 7, under the action of the movable plate 4's own gravity, the other end of the movable plate 4 will drop in height, and then the water above the water trough 5 can be discharged, so as to ensure that the water level is flush with the height of the water trough 5.

[0024] Further, if Figure 3 as well as Figure 4 As shown, the driving component 6 also includes a control box 607 and a water level sensor 608, and the control box 607 and the water level sensor 608 are both fixedly connected to the gantry 8, and the control box 607 and the water level sensor 608 are electrically connected, and the control box 607 and the motor 601 are electrically connected. The water level information is transmitted to the control box 607 in real time through the water level sensor 608, and then the control box 607 transmits instructions to the motor 601, and the motor 601 controls the winding and releasing of the traction rope 7, controls the position height of the water trough 5, and then controls the water level height, wherein different numbers of traction ropes 7 and hinged discs 606 are selected according to the requirements of cost and stability in actual use.

[0025] Finally, if Figure 3 As shown, a plurality of baffles 9 are fixedly connected to the movable plate 4, and the baffles 9 are located on one side of the water trough 5 close to the horizontal device plate 3. The upper and lower parts of the horizontal device plate 3 are fixedly connected with waterproof strips 10, and the waterproof strips 10 are located at the hinged position of the horizontal device plate 3 and the movable plate 4. The waterproof strips 10 are made of soft materials and are used to prevent the movable plate 4 and the horizontal device plate 3 from performing hinged movement. When water seepage occurs at the hinged position of the two, a plurality of baffles 9 can block floating objects on the water surface, thereby preventing debris from clogging the water trough 5. At the same time, it is also convenient to clean up the debris accumulated in front of the water trough 5.

[0026] like Figure 1-Figure 4 As shown, the principle of the automatic adjustment of the water retaining dam for water conservancy and hydropower engineering provided by this embodiment is as follows: when in use, the dam is installed on a suitable river channel, and then the gate member 2 is installed in the water flow channel 101. Water flows through the water flow channel in the dam body 1, and is blocked by the gate member 2. The water flow converges and forms a water level of a certain height, and the water level continues to rise until it exceeds the height of the gate member 2. The water level change is monitored in real time by the water level sensor 608 and transmitted to the control box 607. The water level height is analyzed by the control box 607. When the water level needs to be adjusted up and down, The starting motor 601 drives the driving shaft 602 to rotate, and then drives the driving gear 603 to rotate, and drives the rotating rod 605 to rotate through the driven gear 604. When the rotating rod 605 rotates, it drives the hinged plate 606 fixedly connected to it to rotate. When the hinged plate 606 reels in the traction rope 7, it drives the water trough 5 on the movable plate 4 to move upward. When the hinged plate 606 releases the traction rope 7, it drives the water trough 5 on the movable plate 4 to move downward. The water above the water trough 5 will flow out through the water trough 5, thereby controlling the water level through the water trough 5.
