Embodiment Construction

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0038] refer to Figure 1-8 , a hidden underground dam, including a dam body 1 and a dam frame 11, the upper surface of the dam body 1 is provided with a driving device, a limit device and a telescopic device, and the dam frame 11 is fixedly installed on the upper surface of the dam body 1.

[0039] Such as Figure 2-4 As shown, the driving device is located inside the dam body 1 and automatically blocks and discharges the water in the river;

[0040] The driving device includes a driving mechanism, a maintenance mechanism and a drainage mechanism. The driving mechanism can automatically block water and waterproof. The maintenance mechanism is convenient for the mai...

Abstract

The invention belongs to the technical field of retaining dams, and particularly relates to a hidden underground retaining dam. The hidden underground retaining dam comprises a dam body and a dam frame, a driving device, a limiting device and a telescopic device are arranged on the upper surface of the dam body, and the dam frame is fixedly installed on the upper surface of the dam body. The driving device is positioned in the dam body and is used for automatically blocking and draining water in a river channel. According to the hidden underground retaining dam, by arranging the limiting device, a main gate and an auxiliary gate can be sealed while being limited, a trapezoidal concave block on the main gate is inserted into a limiting groove body, the main gate can be limited, the trapezoidal concave block and the inner wall of the limiting groove body are trapezoidal, the contact area is increased, and the sealing effect is achieved; and the friction force of the contact surfaces of the trapezoidal concave block and the limiting groove body can be reduced through rolling wheels, sliding of the trapezoidal concave block is facilitated, trapezoidal blocks on the auxiliary gate can be slidably inserted in the inner side walls of clamping groove blocks, and limiting can be conducted.

Description

technical field [0001] The invention relates to the technical field of water retaining dams, in particular to a hidden underground water retaining dam. Background technique [0002] A dam is a water-retaining structure that intercepts the water flow of a river channel to raise the water level or regulate the flow; it can form a reservoir, raise the water level, adjust the runoff, and concentrate the water head, and is used for flood control, water supply, irrigation, hydroelectric power generation, and improvement of shipping. To adjust the river regime and protect the bank bed of river regulation. [0003] Existing dams use the motor to drive the rotation of the threaded rod to control the lift of the gate to block water and waterproof the work. The motor and the threaded rod are exposed to the air for a long time, which is easy to cause rust and corrosion, and the threaded rod is prone to breakage, which affects the later stage. Opening and closing work, and the motor nee...
